This video is Part 6 in the Naming Organic Compounds series
This video shows you how to alkene molecules using my puzzle piece approach to IUPAC naming of organic compounds. This video includes a quick introduction to pi bonds and the hydrogen deficiency of alkenes, naming simple alkenes, and naming more complex molecules including substituted alkenes, cycloalkens, and dienes
Many students struggle with naming because they attempt to come up with the entire name at once and often wind up missing a piece or two. After this series you won't have that problem anymore

I'm glad I could help!
Hi, it's my first year in college, and I am now taking organic chemistry. By myself, sometimes I will struggle on some topics because my teacher doesn't always teach us clearly on some topics. Having these videos is very helpful for me to understand those topics. Thank You Leah!!
You're so very welcome, I'm happy I could help fill the gaps for you!
You're the only one who could explain this stuff to me, I've been lost in my lectures for so long. thanks for your help and i will continue to practice and watch more of your videos.
Glad it helped :)
You have no idea what stress you just relieved from me. Thank you so much!! Please never stop

+Leah Fisch Thank you very much!
hi shane, how did you fair in your exam on monday? hope it went well!
Ngani?
5 year update?
Happy to help it click!
I'm from Turkey, so my main language is not even English. But your videos explaining this articles better than my sources. You have my gratefulness.
You're very welcome!
thank you , you are an angel please don't stop helping us
You're welcome, and thank you for your kind words!
Are you struggling in organic chemistry ?
NOW I'M NOT !
thanks
Awesome and you're so welcome!!
Thanks a lot mam.Now I feel that org chem is an interesting subject and you are the one who made me feel so. Thanks again mam.
You're so welcome, I'm happy to help!
Thank you so much leah! You are wonderful! You break it down in a way I can easily understand.
You're very welcome, so happy to help you!
Thanks a lot,at last I learned how to recognise a for
mula as a professor of anaesthesia
Glad I could help!
Watching all your videos.
Doing a rest of chemistry..
Having really bad regrets not finding these videos before my exam
Sorry you found me late in the game, but I'm glad I could help
You give me a helpful video
for my exams (class 10th)
Awesome! Glad to help!
Thanks
Thank you so much for making this video. Naming functional organic compounds is so complicated, but you make it easy to understand. It helps me a lot.You are awesome!!! :-)
You are very welcome! I'm so glad I could help :)
your videos are so helpful to me plz make a video on VSEPR theory
Are you asking about gen-chem level (in depth) or orgo for a review? if review see the hybridization videos in the Orgo Basics tutorial series leah4sci.com/orgobasics
despite the use of terminology I didn't understand such as tertiary, carbo cat ion ETC this video was great
Glad you found the video helpful. As for the terminology you didn't understand, I have some beginner videos on it
hi leah...@ 4:18 can you switch the placement of the 1 and 2 in cyclopentene and count clockwise instead of counter clockwise and still be correct?
Really amazing session 🙂
Good job 👍
Glad you enjoyed it!
Clear, straightforward and informative!
Glad to hear that!
I like all videos of your channel
Nice explanation 👍👍
Thank you so much 😀
I didn't attend my classes today, this helped me Anyway!
Happy to help!
6:22 maam what if the double bond here cannot be on the parent chain?😥😮
If that is the highest priority functional group on the molecule, then we number in a way that includes it in the parent chain. Make sure to keep watching for my final name and numbering scheme around 7:04
In the last example, would it also be correct to call the molecule 2-methylpentene? I don't understand why don't have to write "1-ene" for the other examples in the video but you do for this particular molecule??
Please help.
At which specific point in the video?
Hi Leah Fisch! Thanks for your helpful videos. At 7:05, I don't understand the name 2-methyl-1-pentene, follow at your last videos, it should be 2-methylpentene?
wow, YOU are really GOOD, Leah.. thank you.... great voice, super organized presentation...... congrats! :)
Appreciate that, thank you!
Question: in last example, why we write 1-pentene, isn't 1 assumed?
Thanks for videos by the way:)
At which point of the video please?
@@Leah4sci 7:04
I am very thankful for this and all of your other videos. It was very helpful and hopefully I can ACE my test. I am actually just grade 9. Thank for the book also btw😊😊😊😊😊
Glad the video helped! You're welcome! All the best!
the most informative video on alkenes!! love this and most definitely helpful esp during this pandemic :)
Glad it was helpful!
Thank you for your work! Great explanations.
You're very welcome
you're a life saver omg
Wow
Thanks u sister
Happy to help!
If I have a double bond and a methyl I give priority to the double bond or the methyl?
depends on the molecule in question and the location of the substituents. If everything else is the same then pi bonds take priority over simple alkyl groups
thanks for the quick responses Leah, I appreciate it :)
You're welcome!
Thank you they are more helpful to us
You are welcome :)
You my friend, are a life saver!! muchas gracias
You're very welcome, happy to help!
Leah, thank you very much for these extremely helpful, useful and BRILLIANT videos :-)
You're so very welcome!
Thanks, I wasnt sure how to name it since I get confused when the 2nd line is either facing below or above the structure
You're welcome, glad I could help!
thanks so much for this! Helped me a lot :D
You're welcome, happy to help!
how do you make yourself retain all of this, ithink i am remembering it only for exams then late i forget it
Check out leah4sci.com/memorize for help with that
Great job dear 👏👏👏👏
Thanks!
hello! i wanted to ask why do we write but-1-ene if 1 is already understood and we don’t put it in cyclopentene? is it because butene has two isomers?
I believe the example in this video actually has the double bond on the second carbon, so the parent name is 2-butene. There are two locations within butene where a pi bond could exist, so we want to make sure to specify where that pi bond is resting. In cyclopentene (with no substituents), any location of the pi bond would be considered the first carbon of the ring. Therefore, the 1 is unnecessary.
thankyou very much for helping me in solving many questions in my text book."Leah Fisch thanq
You're very welcome!
Thank you leah..
you're welcome
Should we include the cis trans in the name, so it is trans-hex-2-ene? @2:37
for 2-methyl-2-butene is 2-methylbut-2-ene the same ?
yes, both are acceptable
So helpful,
Thank you so much
You are welcome!
okaaaay! i get it now, that its part of a parent chain, i think thats why i was confused at first! ty :)
You're very welcome!
Thanks Leah ...GOD bless
You're so very welcome!
well done !! .. much better than my doctor
Glad you liked it!
For the last example, can I write 2-methypentene?
It is standard practice to identify the carbon on which the double bond lies. Naming as "2-methyl-1-pentene" specifies that the double bond lies between Carbon 1 and Carbon 2, and not further down the carbon chain.
Thanks a lot for this....
it makes me easy
Happy to help!
fisch u meant lot to meee thankuu forr thiss supereb video oraganic chemistry@@@@@love uuu .........thankkuuu,.,.,..,..,
You're welcome, happy to help!
Thank you very much
I love you ❤❤
You're welcome!
y u not showing how to name the condensed form? i got a quiz about making the ff. condensed and line form. i aced the line form but i sucked at the condensed form!
I have a skeletal video: leah4sci.com/drawing-skeletal-structures-of-organic-compounds/
Work on knowing this forwards and backwards so that you can get questions right no matter the format.
Thank you very much! Very helpful! Every single one of your videos! I subscribed :)
You're so welcome!
good work
thank you!
Thank you for the video!
You're so very welcome!
Good job.
glad you liked it
thanks for this helpfull video
You're very welcome, happy to help!
curious why the alphabetical rule doesn't apply to butene @3:33 ??
how do u mean butene is the name of the chain so that rule don"t apply.if it had a methyl and a ethly then the ethly will come first and then the methly
Emmanuel Hypolite yes thank u my mistake
Substituents at the start of the molecule name get ordered alphabetically, but the parent name stays in place regardless of what letters is contains
THANK YOU VERY MUCH FOR YOU BENEIFICIAL WORK
You are very welcome!
Very nice!
glad you like it!
is your ebook free to download?
It is!
this is really helpful thankx
You're very welcome, happy to help!
do You have a Video tutuorial on Alkyne??
Yes, check here: Leah4sci.com/alkene
Why did you say 3,4-heptadiene ...why did you inlude the "a" in hept?
When you have 2 consonants back to back you add a vowel in between to make it pronounceable
Thanks you're great!
You're so welcome, happy to help!
helped me so much:)
Glad to hear it!
mam is this ebook is free of cost ????
yes!
Wait how do you find the parent chain?
The parent chain is the longest possible contiguous chain of carbons that includes any priority functional groups. For more on organic nomenclature, make sure to view my naming series at leah4sci.com/naming
You have to be a teacher.Thanks.
Not a teacher, just someone who loves orgo. :)
Thanks so much for you :)
You're welcome!
