Quizplus · Accepted Answer

According to the longest carbon chain rule, the parent chain is pentane. The ethylthio group is attached to the first carbon atom of the chain, followed by the second carbon atom from the end of the chain, which has an isopropyl group attached to it. Therefore, the correct IUPAC name is 1-ethylthio-2-isopropylpentane.
