Quizplus · Accepted Answer

The compound has a sec-butyl group (CH3CH2CH(CH3)-) and two ethyl groups (-CH2CH3). The longest carbon chain connecting the nitrogen is four carbons, making it a butane. The nitrogen is attached to two ethyl groups, making it a diethylamine. Since the nitrogen is attached to the second carbon of the butyl group, it is a sec-butyldiethylamine.
