Q.
Reactivity of acid derivatives towards acyl substitution reaction is
AMUAMU 2011
Solution:
The reactivity of acid derivatives towards nucleophilic acyl substitution reactions decreases in the following order $R C O C l>(R C O)_{2} O>R C O O R>R C O N H_{2}$ as the basicity of the leaving group increases as ie, $Cl ^{-}< RCOO ^{-}< RO ^{-}< NH _{2}^{-}$
