Vedclass · Answer

(A) The reaction of sodium $\alpha$-chloroacetate with aqueous sodium nitrite involves the substitution of the chlorine atom by the nitro group,followed by decarboxylation upon boiling with water.The reaction proceeds as follows:$Cl-CH_2-COONa + NaNO_2 \rightarrow O_2N-CH_2-COONa + NaCl$Then,the intermediate $O_2N-CH_2-COONa$ undergoes decarboxylation in the presence of water:$O_2N-CH_2-COONa + H_2O \rightarrow CH_3NO_2 + NaHCO_3$Thus,the final product is nitromethane $(CH_3NO_2)$.

$Cl-CH_2-COONa$ on boiling with aqueous sodium nitrite gives:
