leah4sci.com/organicchemistry/ presents: Naming Alkenes
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

And of course my ebook: "10 Secrets To Acing Organic Chemistry" forms.aweber.com/form/32/15046...
This is the only channel that's helped me satisfactorily with organic chemistry.
I'm glad I could help!
LEAH!! Thank you so much for taking the time to make these videos - they are beyond helpful. You have helped me understand concepts that I have struggled to comprehend for weeks. Thank you so much!!
You're so very welcome, I'm glad I've been able to help you on your orgo journey!

You are so very welcome, happy to 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!
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!
You have no idea what stress you just relieved from me. Thank you so much!! Please never stop

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?
These videos are excellent and very helpful! Sometimes I really think its more beneficial to watch these than go to lecture lol.
Always glad to help! It's always beneficial to have other resources :)
So helpful,
Thank you so much

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
thanks so much for this! Helped me a lot :D
You're welcome, happy to help!
Thank you leah..
you're welcome
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!
Thanks a lot for this....
it makes me easy
Happy to help!
I like all videos of your channel
Nice explanation 👍👍

Are you struggling in organic chemistry ?
NOW I'M NOT !
thanks
Awesome and you're so welcome!!
this is really helpful thankx
You're very welcome, happy to 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
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!
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
Thank you very much! Very helpful! Every single one of your videos! I subscribed :)
You're so welcome!
Thanks a lot,at last I learned how to recognise a for
mula as a professor of anaesthesia
Glad I could help!
wow, YOU are really GOOD, Leah.. thank you.... great voice, super organized presentation...... congrats! :)
Appreciate that, thank you!
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?
Thanks Leah ...GOD bless
You're so very welcome!
Thanks you're great!
You're so welcome, happy to help!
Very nice!
glad you like it!
I didn't attend my classes today, this helped me Anyway!
Happy to help!
Thank you very much
I love you ❤❤
You're welcome!
thank you so much
you're very welcome!
helped me so much:)
Glad to hear it!
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?
Thanks so much for you :)
You're welcome!
thanks for this helpfull video
You're very welcome, happy to help!
thankyou very much for helping me in solving many questions in my text book."Leah Fisch thanq
You're very welcome!
Good job.
glad you liked it
you're a life saver omg
Wow
Thanks u sister
Happy to help!
Thank you so much :D
you're very welcome!
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.
good work
thank you!
Great!
Thanks!
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
thx u so helpful
You're so very welcome!
fisch u meant lot to meee thankuu forr thiss supereb video oraganic chemistry@@@@@love uuu .........thankkuuu,.,.,..,..,
You're welcome, happy to help!
Great job dear 👏👏👏👏
Thanks!
Should we include the cis trans in the name, so it is trans-hex-2-ene? @2:37
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.
thnks :) your videos are helpful
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!
You give me a helpful video
for my exams (class 10th)
Awesome! Glad to help!
Thanks
Ohh thanks 🙏
You're welcome!
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
well done !! .. much better than my doctor
Glad you liked it!
Wow now it's easy🤴🏻
Awesome!
thank on this video
You're welcome!
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
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.
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
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
Hi, just curious about the example @3:32. Could it also be named as meth-2-yl but-2-ene?
Nope. Substituent is methyl it located in number 2 carbon. So don't need to separate the -yl suffix in position
While you can sometimes pull the number to the front of the name, this refers to functional groups. You do not split up the first and last name and so this wouldn't work
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!
do You have a Video tutuorial on Alkyne??
Yes, check here: Leah4sci.com/alkene
thanks
You're so welcome!
for 2-methyl-2-butene is 2-methylbut-2-ene the same ?
yes, both are acceptable
is your ebook free to download?
It is!
i think i love you :) thaaannnkkkkkkk yyyooouuu
Aww you're so welcome!
tx. waiting new tutos about org
you're welcome
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
شكرا جزيلا 👏👍👍
You're very welcome!
@@Leah4sci 💖💖
You are Awesome !! May Allah Bless you !!
Thank you!
mam is this ebook is free of cost ????
yes!
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
3:11

U sound sad
Why do you say that?
Well compared to your earlier videos
