The alcohol function has in general low priority when found with other functional groups. It is frequently named as a secondary function.
MAIN FUNCTIONThe main chain is the longest containing the hydroxyl group (OH).The name of the main chain is suffixed with -ol.The OH localizer should be the lowest possible number.Non-systematic, trivial names can be used in the case of common, simple alcohols.
