(a) The structure of the compound is as follows:

Bond structure of compound (a)

(b The longest carbon chain contains seven carbon atoms and two methyl groups are present on carbon 3 and 5.

Therefore, the name of the compounds is 3,5-dimethyl-1-heptanamine or 3,5-dimethyl-1-heptylamine.

(b) The structure of the compound is as follows:

Bond structure of compound (b)

In the compound, the nitrogen atom is attached to the two ethyl groups and one cycloheptyl group.

Therefore, the name of the compounds is N, N-diethylcycloheptananime or N, N-diethyl cycloheptylamine.
