Which of the following is the correct IUPAC name for an alcohol derived from a six-carbon alkane?

The correct answer is Hexanol, which correctly identifies a six-carbon alcohol derived from hexane. In IUPAC nomenclature, the suffix "-ol" indicates that a hydroxyl (-OH) group is present, which is characteristic of alcohols. Since hexane is the parent hydrocarbon with six carbon atoms, the alcohol form is referred to as hexanol.

The inclusion of "hex" signifies the six carbon atoms, and the "ol" suffix indicates the functional group is an alcohol. Therefore, the full name "hexanol" efficiently conveys both the structure and the functional group of the compound.

Other options do not fit the criteria of being an alcohol derived from a six-carbon alkane. For instance, "hexanoic acid" refers to a carboxylic acid with a –COOH group, not an alcohol. "Hexene" indicates an alkene, which contains a carbon-carbon double bond rather than a hydroxyl group. Lastly, "hexane" is the base alkane without any functional groups. Thus, only hexanol accurately describes the compound in question.
