STRATEGY
First identify the alcohol-derived or amine-derived part, and then assign the name.
(a) This ester is derived from propyl alcohol and butanoic acid. It’s name is propyl butanoate.
\quad \quad\quad\quad\quad\quad \ O\\\underbrace{CH_3CH_2CH_2\overset{||}{C}} -\underbrace{OCH_2CH_2CH_3} \quad\quad\quad \text{Propyl butanoate}\\ \quad{\text{Butanoic acid}}\quad\quad\quad{\text{propanol}}(b) This amide is derived from dimethylamine and benzoic acid. It’s name is N, N-dimethylbenzamide.
