I have been trying and trying and trying to understand IUPAC nomenclature----about to pull my hair out until I FINALLY found you! Thank you so much! I can finally take a breath and finish my chem homework. :) ahhhhhhh
Leah you are my personal tutor it look like when I need you I just consult you watching your video is like talking to you one on one and you listen to me and give me what I want
No. In this example, the alcohol group is NOT the highest priority functional group in the molecule. The ketone is the higher priority group and therefore gets named in the suffix ending as "-one". When named as a lower priority substituent, the alcohol gets named as a "hydroxy" group. For more on Naming Organic Molecules, make sure to view my entire naming tutorial at Leah4sci.com/Naming. I also have a quick reference guide to naming various functional groups at Leah4sci.com/Functional
@@Leah4sci Thank you so much for clarifying. I'm studying Biomedical Sciences at University and currently doing a module on biological chemistry and this topic pops up on the exams a lot.
While it's pretending to be an isopropyl group, it's actually just a methyl group coming out of the bent parent chain. See how I highlighted to follow the parent molecule
No, that would not work. The longest carbon chain in that particular example is 7 carbons, and it would include the group that you are calling an isopropyl. Therefore, the heptanone parent chain here can NOT have an isopropyl substituent. It only has the two methyls.
Some professors do teach to drop the middle 'e' and only to place it at the end. This is a small technicality, but do make sure you always name things in the way your professor prefers.
Thank you for these videos. I am learning organic chem for the first time and have began to love it due to these videos.
That's wonderful to hear! (It's my secret mission to make everyone love orgo!)

Oh no, leave your hair on your head!!! So glad my video helped you finish up!
Why would it not be 2-cyclohexene-1-one at 5:48?
Leah you are my personal tutor it look like when I need you I just consult you watching your video is like talking to you one on one and you listen to me and give me what I want
Oh wow, I'm so happy to hear how much my resources are helping you to understand and hopefully even enjoy Orgo.
Absolutely
Your videos are really awesome. You make things so easy to understand. Thank you.
Im in nursing school getting my BSN
You're so very welcome, happy to share!
At point 6:43, shouldn't the OH group be regarded as 'Ol' instead of an hydroxy? Thank you
No. In this example, the alcohol group is NOT the highest priority functional group in the molecule. The ketone is the higher priority group and therefore gets named in the suffix ending as "-one".

u disserve millions😍
Aww thanks!
Amazing way of teaching !! 🙆🏼
Glad you like it!
Hi your video are really helpful to me
Glad to hear that!
I love this video. Very comprehensible
Glad it was helpful!
At 5:47, the example of cyclohex-2-ene-1-one. When should I use the prefix of alkene, when it's time to use suffix?
In what instances would you use the prefix "oxo-" for the ketone?
asheard09 If an aldehyde or carboxylic functional group is present along with the ketone, the ketone becomes an oxo- prefix.
oxo is used when a ketone is not the highest priority group on the molecule, for example in the presence of a carboxylic acid
Big help for my exam ;) thankyou Ms. Leah
cool
You're so very welcome, happy to share!
Awesome video
Thanks!
Thanks alot for your help!
You're so welcome!
You are so helpful:) thank yo sm you literally saved me from failing my exam T-T
I'm so glad you liked the video! You're welcome. :)
At 2:33 Can I name the compound as 3-Methylbutan-2-one?
Yes, that is the preferred IUPAC name too!
Ryan Wayland Thanks man :)
Yes, both forms are acceptable
Great stuff!
Thanks!
Thank you so much your videos are so helpful!
You're very welcome!
at 3:39 can you also say 5,6-dimethylheptane-2-one?
Yes, both options are correct
3:19 there is an isoprophil?
While it's pretending to be an isopropyl group, it's actually just a methyl group coming out of the bent parent chain. See how I highlighted to follow the parent molecule
@@Leah4sci my comment is from 6 years ago lady, at this point of my life i will thankfully never need or study chemistry for the rest of my life😂
Can I say 5-isopropyl-5-methylheptanone rather than 5,6-dimethylheptan-2-one?
No, that would not work. The longest carbon chain in that particular example is 7 carbons, and it would include the group that you are calling an isopropyl. Therefore, the heptanone parent chain here can NOT have an isopropyl substituent. It only has the two methyls.
@@Leah4sci Ok I got it. But what if I said 5-isopropyl-5-methylpentan-2-one, Will it be right as 5-isopropyl-5-methylheptanone?
Thank you so much ❤
You're welcome!
The example in 5.50 min should be named as cyclohex-2-en-1-one. We need to drop the letter e in the suffix -ene
Some professors do teach to drop the middle 'e' and only to place it at the end. This is a small technicality, but do make sure you always name things in the way your professor prefers.
@@Leah4sci okay thank you so much
In 2:34, why didn't you put it in alphabetical order? B in butanone comes before m in methyl.
Follow the pattern of: Prefix, First, Last, Suffix
butanone is
but: first
an: last
one: suffix
methyl is a substituent and comes before the first name
can i call it 5,6-dimethylhept-2-one
at which point of the video?
Very good
Glad you liked it!
very nice
Thank you

Hey why don’t t you do naming of heterocyclic compounds🥲
It just hasn't come up
