Vedclass · Answer

(C) In acyl compounds (i.e.,acyl chloride,acid anhydride,ester,and amide),the $RCO-$ group is the same; thus,reactivity depends upon the nature of the leaving group $Z$ (i.e.,$Cl^-$,$RCOO^-$,$R'O^-$,$NH_2^-$,etc.).If group $Z$ is a weak base,it acts as a strong leaving group,and the reactivity towards nucleophilic substitution is high.The order of basicity of the $Z$ groups is:$Cl^- Since the leaving group ability is inversely proportional to basicity,the order of reactivity is:$RCOCl > (RCO)_2O > RCOOR' > RCONH_2$Therefore,the correct order is: $Acyl \ chloride > Acid \ anhydride > Ester > Amide$.

The relative reactivities of acyl compounds towards nucleophilic substitution are in the order of
