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)
Thanks a lot this helped
No it's actually for first year of uni, I forgot almost everything at A level After reading your reply, it's coming back to me now
