Question

Out of the following which is most and least reactive towards nucleophilic substitution respectively?

{\text{C}}{{\text{H}}_3}\mathop {\text{C}}\limits^{\begin{array}{cccccccccccccccccccc} {\text{O}} \\ {||} \end{array}} {\text{OC}}{{\text{H}}_2} - {\text{C}}{{\text{H}}_3}, {\text{C}}{{\text{H}}_3} - \mathop {\text{C}}\limits^{\begin{array}{cccccccccccccccccccc} {\text{O}} \\ {||} \end{array}} - {\text{Cl}}

{\text{C}}{{\text{H}}_3} - \mathop {\text{C}}\limits^{\begin{array}{cccccccccccccccccccc} {\text{O}} \\ {||} \end{array}} - {\text{NH}} - {\text{C}}{{\text{H}}_3}, {\text{C}}{{\text{H}}_3} - \mathop {\text{C}}\limits^{\begin{array}{cccccccccccccccccccc} {\text{O}} \\ {||} \end{array}} - {\text{O}} - \mathop {\text{C}}\limits^{\begin{array}{cccccccccccccccccccc} {\text{O}} \\ {||} \end{array}} - {\text{C}}{{\text{H}}_3}
