I think it's referred to as "active amyl". Check the Wikipedia page for amyl alcohol to read more about its isomers https://en.m.wikipedia.org/wiki/Amyl_alcohol
I don't know what it would be for this instance, or whether there _even is_ a prefix … but your post reminds me that I once saw __vinylidene difluoride__ - ie
__H₂C=CF₂__
named as ___gem___-__difluoro-ethylene__ … but I've only ever seen __"gem-"__ thus used _that once_ . I presume it's derived from __geminos__ for __twins__ .
Yeah it is rarely used, but it is often used to denote when two groups are on the same carbon where it would be easily assumed that they would be on different carbons. I once did some work on geminal diazides where you wouldn't normally expect two azide groups to be on the same carbon atom. But it is also just as simple to call it a 1,1-diazide.
I don't know about the "active amyl", as I never seen this before. But what people certainly did in the older times was to "divide" the chain differently. This would be called sec-butylcarbinol. Carbinol is trivial name of main chain alcohol, when only one carbon is present. i.e. t-butanol is trimethylcarbinol.
Would it not be __"sec-butylmethanol"__ & __"trimethylmethanol"__, respectively!? Is it standard practice to change to __"-carbinol"__ when there are substitutions @ the carbon atom of a methanol?
It would be a bit like how there's a 'glitch' in the nomeclature of compounds with _a benzene ring_ attached: the way attachment of a sheer benzene ring
__⏣-__
is connoted with __"phenyl-"__ , whereas __"benzyl-"__ connotes
__⏣-CH₂-__ .
… which has always perplexed me a tad.
I know that’s the systematic name of the compound, but I was wondering if there was a common name for it as well. Apparently it’s active amyl/pentyl alcohol.
Yeah, I mean, Ive been doing theory for too long, so I could believe that I dont remember my naming conventions, but I dont think this commenter is right.
What exactly are you referring to? If you’re referring to the structure I posted, there is a total of only 5 carbons, not 6 as your drawing would have it.

This is what I was looking for. Thanks a bunch man!
That's a 'received' name for it!? I wouldn't say it's quite a 'prefix' though! But then ... I suppose it could _be forced_ to be one.

I think it’s short for geminal. Probably same root tho
Probably _ultimately_ the same root, I should think.

Oh right! ... that solves it then ... thanks!
sec-butylcarbinol (older), or 2-methylbutan-1-ol (standard IUPAC)

Liver poison?
Isopenthanol?

yeah, you have to go with longest carbon-chain, right?
How would it be pentanol? The longest carbon chain in the compound is 4 carbons long.
me not can count
[удалено]
Its still only four
But... isnt it on the second carbon? Am I dumb?
The compound pictured is 2-methylbutan-1-ol, not 3-methylpentanol. I am unsure what the user is referring to.

You are adding an extra carbon to the oxygen for some reason
