Are you struggling with organic chemistry? Download my free ebook "10 Secrets To Acing Organic Chemistry" here: leah4sci.com/orgo-ebook/
This video is Part 10 in the Naming Organic Compounds series
This nomenclature tutorial video takes you through the IUPAC rules naming compounds containing an OH as the highest priority functional group. Examples includes simple alcohols, substituted alcohols and even diols
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
Note: The correct name for the structure at 4:25 is 3-penten-2-ol. You may drop the final "e" when naming an alkene that is not the highest priority functional group on the molecule.

so useful. I found naming organic compound boring before, but after watching your video, my interest has been greatly arounsed. Thank You!!!!
You're very welcome, glad you like it!
you make such a complex chemistry simple and easy to understand. thanks a lot.
You're very welcome, so happy to help clear it up for you!
thank you so much Leah, its very helpful to watch these videos.
***** yes.
You're so welcome!
In Rwanda all chemistry students love u bcz u have made a complex subject as simple as possible to learn. Thanks very much
you're so welcome
thankyou so so much mam... you are the best teacher out there...
Aww thank you!
love the call back to previous videos - thanks.
It's a compliment - overall you're videos are the best because of your timing, organization and professionalism. I've (likely) literally gone through every science channel on youtube that has orgo content and yours is the best by far, it presents the information in a clear and concise way such that not only is it easy to understand, but if you address a concept that is key to the current video but not addressed in this one, you quickly reference the other video and move on - that way everyone is taken care of. That and you don't talk down to us - that's big. A lot of channels try to be flashy or use a tone that feels like I'm being talked down to - I'm not a child, I just want to learn. We appreciate your efforts and thank you. I'm saving up for bootcamp to not only learn but show my gratitude.
Thanks so much for this, I really appreciate it and am happy I was able to help!
thank you so much
you are way better than my chemistry teacher
everyone in my lecture watches your video xx
So happy to help!
(5:09) how did you determine the information that would go in the brackets? I was slightly confused how you determined the number of unique carbons on the chain.
C outside the first cycle bridge head (lower numbers) then C outside 2nd cycle (higher number) then C inside the bridge head
I have a video on this specifically in my nomenclature series: leah4sci.com/naming
Thank you!!! This helps out tremendously!!! :)
You're so welcome, happy to help!
It really help me.thanks you very much
Happy to help!
At 5:12 you start describing the unique carbons on each of the rings. Why are carbons numbers 3, 6, and 7 considered unique?
Perhaps unique is not the right word. What I meant to say here is carbons on that side of the ring not being shared by another ring
Why isn’t the 4 a bridgehead carbon? In 5:47
Carbon 4 is a bridgehead carbon. Remember, in the molecular name, the numbers in the brackets specify how many carbons are unique to each ring portion. Those numbers are not locants.
Thank you
You are very welcome
Helpfull ........ Ty
you are welcome
Thankk You so much Ma'am. :)
You're welcome!
You Should have added spiro too..Overall good! Keep it going
Thanks for the feedback! Glad you liked it
I was wondering whether you made a mistake on counting the first carbon at 2:11? Since the alcohol has the higher priority than alkane, therefore, I think that you should count the first carbon from the left?
At 4:25, I think that it should be 3-penten-2-ol because I can search nth on the internet when I type 3-pentene-2-ol
Thanks for watching and asking! There is not a mistake in the example at 2:11. The longest continuous carbon chain is three carbons in length. The alcohol can only exist on carbon 2, no matter which direction you begin counting in. At 4:25, I will concede your point. That “e” might only be used at the end of a name and not in the middle of one. Since the highest priority functional group is an alcohol, we can drop the final “e” when naming the alkene group.
for the one where you got 3-pentene-2-ol, can you also write pent-3-ene-2-ol and also can u elaborate on when to drop e and when not to? Thanks
thanks. i love your videos
The correct name for the structure at 4:25 is 3-penten-2-ol. You may drop the final "e" when naming an alkene that is not the highest priority functional group on the molecule.
Thx it's very helpful for me🙏
In 2020😅oh no
You're very welcome!
thank u very much
You're welcome!
thanks
You're very welcome!
useful...........thanks
You're welcome!
In 3:46 can it also be named as cyclohexan-1,2-diol?
Yes
Yes, these are 2 different correct ways to name the molecule
Thanx Leah..u d best
You're welcome!
Other sources say it’s 3-penten-2-ol.. Which is the correct one at 4:25
depends on how strict your prof is. technically, 3-penten-2-ol is more correct, to follow a constant rule of always dropping the anE.
Thanks for asking, that “e” might only be used at the end of a name and not in the middle of one. Since the highest priority functional group is an alcohol, we can drop the final “e” when naming the alkene group.
fuuucking hell did this on second lesson of A level chem im lost...i still am lol
Yikes! Lost isn't good. Try going through the video again on a slower speed
What ?...if OH is not preffered group
Then it becomes a substituent with the hydroxy prefix
Leah, wouldn't it be 3-penten-2-ol, instead of 3-pentene-2-ol; you may google it!
Yes, the correct name for the structure at 4:25 is 3-penten-2-ol. You may drop the final "e" when naming an alkene that is not the highest priority functional group on the molecule. Thanks for catching it!
Urgh this is so hard
Keep practicing! Watch the video a few times if necessary, but don't give up!
You shouldn't help a Luciferian

Can i send you a message in WhatsApp? I just want to ask something related in naming compound
