Quizplus · Accepted Answer

The parent chain is a pentane, and there are two substituents on the third carbon atom. One substituent is ethyl and the other is methyl. Since the ethyl group has a higher alphabetical priority, it is named first in the name. The methyl group is named second, and its location is indicated by the number 2. Therefore, the correct IUPAC name is 3-Ethyl-2-methylpentane.
