Verified step by step guidance1
Identify the amine group in the structure, which is the nitrogen atom bonded to two alkyl groups.
Examine the alkyl groups attached to the nitrogen. One group is a propyl group, which is a three-carbon chain.
The other group is a butyl group. Determine if it is a 'sec-butyl' or 'tert-butyl' group by looking at the branching. A 'sec-butyl' group has the nitrogen attached to the second carbon in a four-carbon chain, while a 'tert-butyl' group has the nitrogen attached to a carbon that is bonded to three other carbons.
In the image, the butyl group is a 'sec-butyl' group because the nitrogen is attached to the second carbon of the butyl chain, which is bonded to two other carbons.
Combine the names of the alkyl groups with the amine suffix to name the compound as 'sec-butylpropylamine'.
