Identify the longest carbon chain attached to the nitrogen atom. In this structure, there are two chains: one is a propyl group (3 carbons) and the other is a butyl group (4 carbons).
Determine the type of butyl group present. The butyl group is attached to the nitrogen at the second carbon, making it a sec-butyl group.
Recognize the propyl group attached to the nitrogen. It is a straight chain propyl group.
Combine the names of the two groups attached to the nitrogen. The name should reflect the sec-butyl group and the propyl group.
The correct name for the amine is sec-butylpropylamine, indicating the sec-butyl group and the propyl group attached to the nitrogen atom.
