    As an A2 I can only ever remember using -ol in exam papers. Depends on your exam board, but if you are asked to name an alcohol it will contain the suffix -ol, rather than the prefix hydroxy-.

    It's mostly used when you have more than one functional group. So if I have this:



    A name for it would be 2,3,4,5,6-Pentahydroxyhexanoic acid.

    It's the prefix equivalent so use it when the suffix is used, e.g. if there's a carboxyl functional group.
