So glad the video helped you. Good luck in your studies.

I was unprepared for naming these on my exam. I tried studying them afterwards but it never made sense and I was getting so frustrated-this video cleared it up so easily. Thank you so much

You're welcome.

For sec-butyl you can just shift the last part 2 places instead of one.

@ChemHelpASAP

Yes. That works for butyl. If you had a longer chain, then the methyl must move more carbons (e.g., sec-pentyl). Admittedly, the only common time you encounter "sec" is with sec-butyl. You do sometimes see trivial names for 5-carbon chains (the "pentyl" and "amyl" labels are very messy and sec-pentyl is part of that mess). Once you get to 6-carbons, almost everyone shifts to IUPAC nomenclature. The exception is "iso". The idea of an "iso" group is still used for longer chains as well.

I don't think it needs memorization. Sec means there are two carbon atoms attached to the carbon atom in question.

Sir can we say that :- we use iso when 1 degree carbon is concected to adjacent 3 degree cabron ?

@ChemHelpASAP

That works for isobutyl. Note "iso" can be used for longer chains - isopentyl, isohexyl, etc. The "primary next to tertiary" will not work for those longer chains. isopentyl = X-CH2-CH2-CH(CH3)2. isohexyl = X-CH2-CH2-CH2-CH(CH3)2.

Are these all iupac names or are some common names

@ChemHelpASAP

These are all common names, but they are so ingrained into chemistry that they are still very widely used. From my understanding, only tert-butyl is still officially part of the IUPAC system. For example, an isobutyl group would be called a 2-methylpropyl group under IUPAC. sec-butyl would be 1-methylpropyl.

@@ChemHelpASAP Very helpful. Thanks :)

What is the difference between iso and sec? This question still remains unanswered. If we take benzyl group of your examples as R-, thrn you used iso with Isobutylbeneze in which the R is attached to first carbon of 2-methyl-propyl, while in sec-butylbenzene R is attached to second carbon of butyl

But if we have propyl instead of butyl in the sec example which I mentioned above, then we say it is isopropylbenzne, why? Waiting for your reply

@user-mb1bo4zd2c

So let me put in simple words, why do we say sec-butylbenzene but say isopropylbenzne when in both the situations R is attached to second carbon?

@ChemHelpASAP

@@user-mb1bo4zd2c Let's assume that isopropyl was named first. You're correct that going to the isomers for butyl gets unclear. Therefore, whoever was making decisions said that the "iso" isomer is for the methyl coming off the second-to-last carbon from the main chain. So, as you go from isopropyl to isobutyl to isopentyl, the branching carbon gets farther away from the main chain. That still leaves sec-butyl. For sec-butyl, just put the methyl on the carbon coming off the main group. The real challenge begins with the pentyl isomers. I don't even want to get into those. They are messy enough that almost all organic students stop with the butyl isomers. Of course, the real solution to this problem is to use a systematic system like IUPAC. IUPAC also has its issues, but it's better than memorizing unique isomers.
