Question

Quizplus · Accepted Answer

The compound has a chain of six carbon atoms with a phenyl group attached at the fifth carbon atom and a methyl group at the first carbon atom. The carboxylic acid functional group is attached at the sixth carbon atom. Following the IUPAC naming rules, we count the six carbon atoms and name the parent chain as hexanoic acid. We then add prefixes to indicate the position of the substituents. The methyl group is attached at the first carbon atom, so we name it 5-methyl. The phenyl group is attached at the fifth carbon atom, so we name it 5-phenyl. Therefore, the IUPAC name of the compound is 5-methyl-5-phenylhexanoic acid.
