Question

Quizplus · Accepted Answer

The longest carbon chain in the compound is 6 carbons, so the base name is pentane. There are two substituents on the chain, an ethyl group and a methyl group. Since we want to assign the lower numbers to the substituents, we start numbering from the end closest to the ethyl group. This gives us a 3-ethyl prefix. The methyl group is on the second carbon, giving us a 2-methyl prefix. Combining these gives us the name 3-ethyl-2-methylpentane.
