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 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.
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!!
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!!! :-)
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😊😊😊😊😊
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
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?
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.
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
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
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.
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.
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.
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
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

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 , you are an angel please don't stop helping us
You're welcome, and thank you for your kind words!
the most informative video on alkenes!! love this and most definitely helpful esp during this pandemic :)
Glad it was helpful!
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
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
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!
you're a life saver omg

wow, YOU are really GOOD, Leah.. thank you.... great voice, super organized presentation...... congrats! :)
Appreciate that, thank you!
thanks for the quick responses Leah, I appreciate it :)

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?
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?
Thank you leah..
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?

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
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
Thank you for the video!
You're so very welcome!
Thanks you're great!
You're so welcome, happy to help!
this is really helpful thankx

Good job.
glad you liked it
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 for this helpfull video
You're very 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

helped me so much:)
Glad to hear it!
good work
thank you!
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.
Should we include the cis trans in the name, so it is trans-hex-2-ene? @2:37
Thanks so much for you :)
You're welcome!
thnks :) your videos are helpful
You're so very welcome!
Wow now it's easy🤴🏻
Awesome!
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!
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.

Work on knowing this forwards and backwards so that you can get questions right no matter the format.
You have to be a teacher.Thanks.
Not a teacher, just someone who loves orgo. :)
mam is this ebook is free of cost ????
yes!
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
thank you so much
you're very welcome!
tx. waiting new tutos about org
you're welcome
is your ebook free to download?
It is!
for 2-methyl-2-butene is 2-methylbut-2-ene the same ?
yes, both are acceptable
You are Awesome !! May Allah Bless you !!
Thank you!
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
Is this your original voice Leah?
yep, that's me
thx u so helpful
You're so very welcome!
Wait how do you find the parent chain?
