    I don't understand the IUPAC rules for naming alcohols.

    Most of the times we use the suffix -ol at the end of the name of an alcohol.

    However when do we use the prefix hydroxy- ?

    Can someone give examples and please help.
    Thanks.

    I'm assuming this is for Alevel chem, it should be explained in most AS textbooks however for a quick understanding:


    It depends on the functional groups you have within a molecule.
    -ol is used where Alcohol takes priority for the main functional group.

    For example, within a benzene ring, hydrocarbon.
    (Butanol, Methanol, Benzene 1,2,3 - triol)

    However when we have multiple functional groups where a different functional group takes priority within a molecule we use Hydroxy-
    This is mainly for more oxidised groups such as carboxylic acids or ketones/aldehydes.

    (2-Hydroxybutanal or 2-Hydroxypentanoic acid)
