Quizplus · Accepted Answer

According to the IUPAC nomenclature rules, when both substituents are alkyl groups, the names are listed in alphabetical order. However, in this case, the carbonyl group takes precedence over the alkyl groups, so the suffix -amide is added to the name of the parent alkane (propane). The nitrogen atoms in amides are considered part of the functional group, so they are included in the prefix. Therefore, the correct name for this compound is N-ethyl-N-methylpropanamide.
