thanks leah! absolutely love your videos. you go far more in depth than my orgo chem lecturers and your videos are the reason i'm doing so well in organic chem.
The end part of the video is what makes this better than any other videos I have seen. I was always uncomfortable with come up with reagents given final product questions but not anymore thanks to you.
I just want to thank you so much because I’ve been struggling so much with o-chem and so far I have understood everything that you have went over. I truly want to thank you for these videos and tips!!!
wow! you made it so easy!! I love how you cut the chase and just explain the main idea of each topic. I think many college classrooms get boring and unproductive because profs go on tangent and students do not have that long of attention spans to follow it.
I actually took orgo 2 years ago and passed with flying colors thanks to you and your videos. I still watch them because I honestly just enjoy them. They're extremely clear and concise, but still thorough. Plus, your voice is very relaxing. 👍😊
You’re amazing!!!!’ I really appreciate your videos, thank you for sharing this for free. Very helpful!!!!! God bless you, thank you for helping us with organic, you’re the best!!!!!!
Amazing!! This video was extremely helpful. You basically took most of one lecture, put it into a few minutes, and made it very easy to understand. Your videos have helped me a ton with o chem. You are really talented at teaching and creating videos! Thank you so much!!
Your videos are superduper fantastic.When I started my organic course I thought it's a monster... but with your videos I've friend with orgo pall.... Thanks very much,leah!!! Keep up the good work! Teachers like you truly are a blessing... 👌👍❤
@@Leah4sci Four more classes (including biochem so I guess I'm not completely done with ochem...) before I can start working on my masters in nutrition!
Hi Leah thanks for all yours amazing videos. They helped me got an A on my both org chem courses. Now I am using them again for my MCAT preparation. Thank you so much!!!
you're amazing! thank you for going through the basics and how the electrons are flowing. it makes the reactions so much easier to understand but professors just start drawing arrows without explanations
Thank you so much🥺❤️....you are seriously great....thanks to you tube for recommending me this video....I was searching for a good explanation like this❤️❤️
Awesome, so glad I helped! As for the video request, the free videos are what I do as I have time. For more help with this topic, feel free to contact me through my website: leah4sci.com/contact
I have some carbonyl reaction videos posted already. I cover these in even more depth in the orgo study hall leah4sci.com/join (ketones, aldehydes, carboxylic acids / derivatives, protecting groups...)
Ma'am can you make a video on all the reaction mechanisms of organic chemistry of international advanced level(IAL A2) chem? It would be very helpful for me as my tutors don't show me the reaction mechanisms of most of the reactions and so I seek help from youtube. I found your channel in 2021 and from then onwards, my knowledge is improving 😀😀. Can you make a video of the reaction mechanisms? Thank you ❤️.
That would be a very long RUclips video to contain every mechanism studied in undergraduate Orgo.

I do have a video on the reaction and mechanism of keto enol tautomerism in both acid and base. Read the article and find the video at leah4sci.com/keto-enol-tautomerization.
"Same thing happens for alcohol @4:15" was so jarring right after your ice-cream analogy 🤣💀It may have been unintentional, but it was a great way to reel back deep attention midway through the video! Thank you!
Hey Leah, I have been trying to years to get organic chemistry but its only upon coming across your videos that things are finally starting to click. Thank you for your work! What books would you suggest that follow your way of explaining things?
Sorry for the late reply! I'm glad to hear you are understanding! Here are some of my recommendations for orgo resources: leah4sci.com/5-must-have-organic-chemistry-resources/
very helpful, thank you! But can you explain how we know the carbonyl group at the very end is an aldehyde, rather than a ketone? How do we know there is an H present instead of an R group?
I hope you found what you were looking for in this video! If you haven't already, make sure to view my tutorial and cheat sheet at Leah4sci.com/Grignard. For further questions, you can contact me through my website at Leah4sci.com/contact
Please help 1. A compound A reacts with an alkylmagnesium halide B to give the final product C, of formula C5H12O. Dehydration of C gives a compound D which on oxidation gives two products E and F. The later reacts with 2, 4 - DNPH but E does not. However, E turns blue litmus paper red. Compound D decolourises bromine dissolved in carbon tetrachloride. a. Write structures A and B. b. Using appropriate structures, write the sequence of reactions to the final products, E and F. c. Name the compounds A, C, D and F, d. Draw all the possible stereoisomers for each of the optically active compounds in c above.

I was wondering in the very last example of finding out the reactants. I thought gringard agent is added only to elongate the chain without Mg attaching itself to the carbonyl carbon. Can the reactant be cyclohexanone? If you followed the steps of the shortcut you’d get the same product ?
Cyclohexanone would not work for this example because we want the position of the final alcohol to be on the carbon that is one removed from the ring. We don't want the alcohol directly bonded to the ring. For help with questions like this and more, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/
hey ! we have conversions in organic chemistry. like we are given the reactant and the product and we are supposed to convert the reactant into the product anyhow. thing is that i have learnt the individual reactions but still can not effectively do conversions. can you please suggest what should i do to do them effectively?
for example we were given to convert ethanol to but-2-yne . i was able to convert it into but-1-yne but could not convert it into but-2-yne. i dont understand how to bring the triple bond to the 2nd carbon.
At 8.33, y do we need break either side when carbon has only 3 bonds in the first place?Y can't we just add on another bond n let it be sp3 hybridised?
Thanks for watching and asking! First, the carbon bound to the alcohol group has 4 bonds to begin with. The rules for drawing bond-line structures tell us a hydrogen is also bound to that carbon in addition to the oxygen and other carbon groups. Second, the reason we are breaking a bond in this example is because we are working backwards to predict the reactants. A Grignard reaction is important for its ability to elongate carbon chains by the formation of new carbon-carbon bonds. To work backwards in a Grignard reaction, we must think about breaking bonds rather than forming them.
Thanks for asking! After the reaction, the magnesium and iodine from the Grignard reagent remain in solution as a positively charged Mg-I unit. It is common to ignore the Mg-I on paper because it is not a part of the primary organic product.
Hey, iam Egyptian so i speak Arabic, i try to understand you and then i understand 60% because of language. Can you help me if you wrote explanation and send me it?? ❤️❤️
Making the videos is what I do in my spare time, so I don't have time to send you a written explanation. However, you can turn on closed captioning and slow the speed down to help you understand better. Thanks for watching!

Because OH is attached to a secondary carbon

Did explain it when using excess of Grignard to alcohol and it gives esters instead of ketone or aldehyde
