Quizplus · Accepted Answer

The correct IUPAC name is 2-methyl-4-penten-2-ol. This name indicates the presence of a double bond between the 4th and 5th carbon atoms (penten), a methyl group on the 2nd carbon atom (2-methyl), and a hydroxy group on the 2nd carbon atom (ol). The other answer choices do not correctly indicate the location of the hydroxy group.
