Quizplus · Accepted Answer

The compound has a triple bond between carbons 4 and 5, making it a -yn ending. It also has a hydroxyl group on carbon 2, making it a -ol ending. The longest carbon chain is heptane, with the triple bond at the 4th carbon, giving the name 4-heptyn-2-ol. Choice A has the incorrect placement of the triple bond, choice B has an extra carbon on the double bond, choice C has the incorrect placement of the hydroxyl group, and choice E doesn't account for the triple bond.
