- Are you struggling with organic chemistry? Download my free ebook "10 Secrets To Acing Organic Chemistry" here: leah4sci.com/orgo-ebook/
This leah4sci.com/organicchemistry/ tutorial teaches you how to draw organic molecules using line structure or skeletal structures, how to read/understand and count the atoms in this new structure, and how to convert back from a skeletal structure to a Lewis Structure or Condensed Molecule Structure
Many students struggle with organic chemistry because they try to memorize rather than understand the concepts and mechanisms. My goal is to break down the concepts so that you can understand and apply them to your homework, quizzes and exams
If you enjoyed this video please show your appreciation by giving me a thumbs up, and subscribe to my channel for quick access to all new tutorial uploads
I will be creating quizzes to help you study the concepts in this quiz. These will be available on my website shortly

I believe that certain teachers have forgotten how to teach... Thank you for being one of the great ones and for helping us consistently! You are appreciated!
daric nd agreed. some go too fast
You're so welcome, and thanks for your kind words!
I literally thought of quitting my organic chemistry class within two classes of it. My professor is a bit unorganized, so this was a life saver for me. Subscribed, liked, commented, and now I will check every video you have for help. THANK YOU.
Oh wow, I'm sorry you had a rough time in orgo, but I'm happy to know I was able to help you through it!
I never understood the whole number of hydrogen's in a skeletal formula idea, but now I get it. Thank you so much
You're very welcome!
I was so incredibly confused and you explained it so amazingly well!!!! Thank you for these videos. Amazing help!
You're so very welcome, happy to share!
OMG Ms. Leah, My Chem exam is to tomorrow at 9am ..Im am so blessed that I , some how, found your tutorial videos. Now I completely understand. Now I feel more at ease about the exam. This is a Chem/ online coarse too. YES!!!!!
Hi there, because of your tutorial, I passed with flying colors. I struggled with skeletal structures for some reason. Thanks so much.
Wow that's fantastic to hear! So happy I could help!
So grateful! You make the Organic Chemistry look so much easier! thank you so much

This video was very helpful! Cleared out any tiny doubts I had! Thank you!
So glad to hear that and yay for clearing up your doubts!
Wow! This clears up a lot of saved me the headache of trying to understand my textbook. I'll definitely refer back to your channel as I continue through chemistry!
Awesome, so glad I was able to help!
Oh wow, I'm glad I found this page. I've been sick and missed my chemistry class. This video has really helped me catch up on what I've missed. Thank you so much.
So glad I was able to help you fill the gaps after your illness!
PRETTY DARN GOOD!!! Just starting organic your videos are keeping me on top of my game. Great job.
So happy to help you!
Hi Leah, people like you make this world a beautiful place to live. Thank you.
Wow, thanks so much!
Thank you so much, I will be checking your videos out this entire semester for sure!
You're so welcome!
Thank you! Just made this easy and I learned some things I didn't realize I didn't know. Great video.
You're so welcome, glad to teach what you needed and more!
you really helped me understand a lot of details I was frustrated with, my first week of organic chem has been a nightmare for me...reading the book for 5 hrs straight, trying to understand...then going to class realizing I still didn't get it. I wanted to cry. but this helped me learned the basics so now other things will make more sense to me. Thank you Leah.
Oh no, I'm sorry orgo was so rough for you, but I'm glad to hear that I was able to help it make sense for you!
Omg this just completely made it easy for me to understand this. Thank you!
YAY, so happy to help you understand!
Thank you for breaking this down. I understand it much better now...
I'm glad I could help!
thank you Leah, the video is really helpful...you enlightened me
on what i couldnt understand before..thanks!!!!!!!!!!!!!!!!
I'm so glad to hear that!!! Happy I could help!
Thanks for your help...I never really understood this concept well until i listened to your video.
You're welcome, glad it cleared things up for you!
maan i've been looking for this for so long, thank you
You're very welcome!
Thank you Leah again for your time on this stuff..I have a few years in between doing general chem and then starting this Organic chem. I feel like professor teaches nothing, so this is the best way for me to learn.
I'm sorry you had a bad experience with your teacher, but I'm glad I could help fill in those gaps.
Currently taking Biochem without any O-Chem background. Khan Academy
was helpful, but your video answered all of the questions that it left
me with, and you may have saved my semester (and hours of googling).
Thank you, you're a rockstar!
You are so very welcome, glad to help!
this is so helpful. I was feeling nervous as in lecture i was completely lost but thanks to your explanation it makes so much sense. I have learned new trait today which is Analyzing rather than memorizing. thank you so much
I'm so glad to help you through your class and that you learned to understand, not just memorize!
Loved this video made me understand it so well in just a few minutes thank you!
You're so very welcome!
Oh wow i definetly appreciate what your doing. This made things a whole lot easier for me!! Excellente

This is so helpful I will continue to go to your channel for extra help and practice. Hopefully it will help me get a decent grade in orgo. I'm definitely subscribing!!
So happy to help and thanks for subscribing!
Leah, I never thought I'll say this to anyone but.. I LOVE YOU!
lol, thanks so much!
my biology course requires me to take ochem classes and my prof is a mess. i cant understand what his saying most of the time and his pen craft is also a mess. THANK YOU!! you save me having to read books at the library again.
I'm sorry to hear that you don't have a good professor for this course, but I'm happy to know that my videos are helping you so that you can still get through this class
Hey Leah, I have a quick simple question on the diagram of Butanoic Acid.
On the 3rd carbon, which is a CH3, in the line drawing I'm only seeing 2 Hydrogens and not three on that carbon. Where have I gone wrong?
I'm seeing a carbon met with only two bonds, so I have the thought process that would mean there would be 2 hydrogens instead of 3. Where am I going wrong?
Thanks Leah! This is perfect
You're so very welcome!
Starting A - Levels in september,your videos really make it easier to understand the concepts of chemistry... thank you :)
So happy to help!
This video literally answers EVERY question I had about chemistry!!! Thank you!!!!
***** I take grade 11 chem and bio but we haven't learned this yet, I'm just very curious about it.
***** Probably, I refer more to it as Biochemistry.
Awesome, so happy to help!
I've read the book, done the homework on my 3rd chem. class and i think i LEARNED more in one of your 5 minute videos than i have in a class..
Thanks!
Yay, so glad I could help!
Best explanation ever... really thankyou very much!
Glad you enjoyed it!
thank you so so much! you honestly teach way better than both of my chem teachers combined
You're so very welcome!
Leah! You are awesome! You have made this concept very clear!
You're very welcome, so happy I could clear it up!
Thank you for being plain and simple.
You're very welcome
You're amazing, this was extremely helpful. Thank you so much!
You are very welcome, happy to help!
thanks for this leah. I really appreciate it.
You're welcome!
Good easy to grasp explanation! Thanks :)
You're welcome!
Thanks for the good tutorial, helped someone who is in a biology class with little background in chemistry.
Yay, so glad I could help!
That video was great, just wondering if the molecule drawn at 7:33 would be 2,3-methyl-propane?
Thankyou for this. has helped me ALOT. THANKYOUUUUUU!!
You are SO very welcome!
thank you very much finally now i know how do i work from lewis structure to skeletal formula❤
Glad I could help!
Leah u saved my life. Thank u so much. :D
You're very welcome!
you r the best. I have no words, how much u made that stuff so easy...
Yay, I'm so happy to have helped you!
Amazing! My teacher wasn't so good at explaining this but you sure were!
So happy to help!
thank you so much for this video God bless you!!!!!
You're welcome! :)
Hey Leah, are you sure butanoic acid is CH3CH(CH3)CH3*CO2H? The CH3 group before the CO2H would have five bonds here, 3 with H and 2 with the other C atoms. Based off what you're saying it should be CH3CH(CH3)CH2*CO2H... or is there an exception?
at which point in the video? Butanotic acid would be CH3(CH2)2CO2H or CH3CH2CH2CO2H
Superb! Thanks Leah!!
You're very welcome!
Totally awesome! Thank you!!
You are very welcome!
this was a great explanation! thanks!
You're very welcome!
YOU ARE AMAZING thank u so much this is really helpful
You're very welcome, happy to help!
So helpful! Just a couple questions: how did you know to add a lone pair to the N at 12:12? Also how did you know to make those double bonds at 12:41?
This video is more about the skeletal aspect of the structure. Your questions are covered in my intro to orgo series: leah4sci.com/introorgo
I don't know much about chemistry or how to even word this question properly but I always wondered how you number each position and if it's a different structure why numbering changes direction. Like your cyclohexane example, why does the "1" go at the top left. I don't even expect a reply cuz I understand if there's a nitrogen in it or certain functional groups that might change direction I don't know enough I acknowledge some of it but I don't expect the detailed response. Maybe a taste would help?
I'm sorry, but I don't offer tutoring through RUclips comments. For help with this and more, I recommend joining the organic chemistry study hall. Full details: leah4sci.com/join
Thanks mam for this awesome tutorial video.It has really helped me a lot.
You're welcome, I'm so happy I could help!
this is a great video!!!! So happy I found your channel, I might actually pass Organic now!!!! lol YAY!
WOOHOO! Glad I could help!
While there were a few errors, it was still a very good and informative video, and it really refreshed my memory for drawing skeletal structures. Thank you 😊
You're welcome. What are the errors you are referring to? (Timestamp please). Thanks!
I just started organic chem and began to get confused on the drawing of line structures. Your video has cleared up some of the problems I was having.
Thank you.
So happy to fill those gaps and clear it up for you!
The video is just awesome I have searched for so many videos but this I founded the best of the best to clear my doubts thank u so much and I hope u will solve my questions in future lovely skill of explanation

Thanks so much and you are so welcome!
Thank you, this was so helpful!
So glad to hear it!
Thank you soo much!!I always had problems with this till now!! :))
You're so welcome!
omg. i might pass o chem...so happy i found this youtube channel. great job :D
Happy to help!
thank you so much. really useful!
You're welcome!
That's what I figured, just wanted to double check. Thank you!! Awesome video by the way. :-)
You're so welcome!
Thank you! Hands up. I now understand ☺☺☺
You're welcome!
Your videos are so helpful! Thank you so much! I had a question about the last example, Glutamic Acid. According to the structure of the video, the condensed formula would be C5H8NO4. I wanted to double-check my answer so I searched on google and it says that the formula for Glutamic Acid is C5H9NO4. So 9 Hydrogens instead of the 8 that I count according to the skeletal/Lewis structure in the video. Could you please help me clarify this? Thank you in advance!!
Yes, of course. This is a great question! The overall charge of glutamic acid will change based on the pH of the solution it is in. This particular amino acid has three ionizable groups - the carboxy group, the amino group, and the side chain. By comparing the pH of the solution to the pKa of those individual groups, we can determine whether each will be protonated or deprotonated and also what the overall charge of the molecule will be. For more on this, you can read my tutorial at leah4sci.com/amino-acid-charge-in-zwitterions-and-isoelectric-point-mcat-tutorial/
@@Leah4sci Thank you so much for the explanation!! :)
5:04 - I'm kinda confused. If the molecule of Pentane has the fifth carbon at an angle, it would look like methylbutane. So how to I know (when the carbon is at an angle like that) if its Pentane or Methylbutane?
Great question! if you can trace a path through the entire chain without lifting your pen, it's one chain, if you have to lift because of a branch, it's a substituent
Hi, what is the name of the compound at 10:07?
thank you very much. big thumbs up for you :)
You're welcome! :)
highly informative with great explanation
Glad you liked it!
Perfect! thank you!
You're so very welcome!
This video was very helpful !! Can you please post a video about chiral and fisher projections? Also about ring flip and chair conformation (chair, half-chair, and boat). This is what I am studying in orgo class now! Thanks a lot!!
You're welcome! You can use leah4sci.com/syllabus to match up my resources with what you're studying.
your explanation was the best.

really really helpful thank you
You're welcome, happy to help
very useful . Thank you
You're welcome, happy to help!
very helpful but your number of hydrogen for the butanoic acid example is not the same, 12:40. 11 and 10 are the two numbers of Hydrogen that i was able to count?
Oh wow, thanks for pointing this out, I have a mistake in the drawing. The right-most carbon before the carboxy should be a CH2
Thank You! this was very useful.
You are very welcome! So happy I could help!
Thank youuuu it really helped
