$(CH_3CO)_2O + NaCl \rightarrow CH_3COCl + CH_3COONa$

Vedclass · Answer

(D) The reaction $(CH_3CO)_2O + NaCl \rightarrow CH_3COCl + CH_3COONa$ is not possible. This is because $Cl^-$ is a much weaker base than the acetate ion $(CH_3COO^-)$. In a nucleophilic acyl substitution reaction,a stronger base (nucleophile) can displace a weaker base (leaving group),but a weaker base cannot displace a stronger base. The basicity order is $Cl^- Therefore,$Cl^-$ cannot act as a nucleophile to displace the acetate group from acetic anhydride.
