Alcohol groups get priority in IUPAC nomenclature.

The provided data for this item is incomplete: there are no answer options to analyze, only the stem and a single listed answer.

In general IUPAC nomenclature uses a priority order to decide the suffix of the name when multiple functional groups are present. Alcohol is indeed treated as a suffix (-ol) when it is the principal functional group, but it does not always have the highest possible priority compared to all other functional groups like carboxylic acids, acid derivatives, aldehydes, or ketones. Those higher-priority groups determine the base name and suffix in many contexts, and alcohols come into play as the suffix or as a substituent (hydroxy) depending on the presence and hierarchy of other groups.

If the question were asking whether alcohol is given priority in determining the principal functional group, the answer would depend on what other groups are present. In a molecule containing only an alcohol, the alcohol is the principal group and the name would end in -ol. If a higher-priority group (for example, carboxylic acid) is present, the higher-priority group takes precedence for the suffix, and the alcohol may be indicated as a hydroxy substituent or as a suffix only if no higher-priority group is present.

Thus, without the answer options, we cannot assess a specific multiple-choice choice. Conceptually, alcohols do have a notable priority in IUPAC nomenclature, but they are not universally the top-priority group across all possible functional-group combinations.
