Draw the structures of each of the amines. mark as primary, secondary or tertiary.
a) cyclohexylamine
b) 1-methylbutylamine
c) n, n-dimethylaniline
d) n-methylethylamine

A. Primary.

B. Primary.

C. Tertiary

D. Secondary

Explanation:

Amines are derivatives of ammonia, wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group. A primary amine has one alkyl (or aryl) group on the nitrogen atom, a secondary amine has two, and a tertiary amine has three.

The structures are in the image.

A. As the structure has just one alkyl group, the amine is PRIMARY

B. As the structure has just one alkyl group, the amine is PRIMARY

C. As the structure has two alkyl and one aryl groups, the amine is TERTIARY

D. As the structure has two alkyl groups, the amine is SECONDARY.
