Naming Organic Compounds Series: Video 4
This tutorial video shows you how to name organic compounds with substituents coming off their substituents. This includes the ‘long' version of naming each individual group, and the accepted abbreviations like tert-butyl and isopropyl.

Hi Leah, the videos help me so much, but I was ask to draw an isopentyl cation, isopentyl-2 butyl cation and a 2-methyl-2-butyl cation and rank them, and I’m so confused.
I can tell that pent is 5 Carbon, yl is a sub and iso look like the Mercedes sing, but can’t drew it.
Hi,
can this also be called 5-isopropyl nonane?
-thanks
At 1:54 could you not name the methyl propyl branch isopropyl instead of 2-methylpropyl ?
This video helped clarify my questions on the structures. Thank you!
Regarding 4-(1-methylethyl)-octane couldn’t you drop the 1 as that’s the only place the methyl group can go? If in doubt is it always best to add a number?
What do you use as reference? I went to IUPAC website but didn’t find it very useful.
I like your videos. To the point.
I’ve seen it named without a number. I personally would keep the number to avoid any potential confusion
Much more interesting and understandable than a 4 roomed packed class.
Thank u for this video, I was having a trouble in understanding this topic.
Well now I am surely getting 6 marks in my finals..
glad I can help Sanket
It’s not 4-(ethyl-1-methyl) because of the alphabetical rule?
Be careful Clarice. Ethyl is considered the parent of the branch and so is not alphabetized with the substituents ON the branch
thank you for a very clear info from you. most appreciated:)
You are very welcome SyahirahShaff
Thank you for being awesome! Seriously saving my life and making this process towards medical school a little more smoothly. So very very grateful to have run cross you on youtube!
Thank you Monica! glad I can help. Are you in orgo right now?
I am in orgo right now, there is so much to learn and I am only on the alkane hydrocarbons 🙁
Thank you! I love you 🙂
You are the best !!! short, simple and to the point
Thank you, what are you studying right now?
Please, do not stop doing what you’re doing. It’s obvious that you love this thing. Your method of teaching is amazing and your help so precious. Your voice is nice too! Thank you thank you thank you 🙂
