Check the name of this compound? - A2

Can someone check if this is

2-hydroxy-2-methylpropanenitrile

(sorry for my bad drawing :3)

Almost. It's 2-Hydroxy-2-methylpropiononitrile.

^^^ where did you get that from. I havent come across that before??

Oh actually it looks like yours is right too. The one I wrote is how I was always taught, but naming nitriles has changed since then.

Oh. Thanks - i thought it might have been different spelling from where you live. I guess not

Nah Wiki lists both of them as names of the compound. Just for extra info, what people actually call that compound is Acetone cyanohydrin, although never say that if you're asked for the systematic name of course.

Ahh. Of course - ive always been told to write the systematic name (it would be quite unusual if i was asked for the common name in an exam)

I just did a quick check in IUPAC's "Principles of Chemical Nomenclature" (seriously this is literally the most boring book).

It appears that your answer is the only correct one as if you use an -ionitrile, you can't have any other substituents (like the methyl and hydroxy groups in your compound). So yeah. IUPAC being IUPAC

My chemical drawing program named it the same as me too, so it's probably a recent addition to the rules.

I see, thanks for your help

So if the hydrocarbon had just a CN would it be -ionitrile?
