If group $Z$ is a weak base, then it is a strong leaving agent and its reactivity towards nucleophilic substitution is high. The order of basic nature of $Z$ groups is
$C l^{-} < R C O O^{-} < R^{\prime} O^{-} > N H_{2}^{-}$
Thus, order of reactivity is
$R C O C l >(R C O)_{2} O > R C O O R^{\prime} >R C O N H_{2}$
$Acyl chloride > Acid anhydride > Ester > Amide$
$C{H_3}COH\xrightarrow[{{\text{Zn(Hg)/Conc}}{\text{. HCI}}}]{{\left[ H \right]}}C{H_3}C{H_3}$ શું હશે ?
[જ્યાં, $\left.{Et} \Rightarrow-{C}_{2} {H}_{5}{ }^{{t}} {Bu} \Rightarrow\left({CH}_{3}\right)_{3} {C}-\right]$,
