Vedclass · Answer

(B) The sulfite ion $(SO_3^{2-})$ is an ambident nucleophile.In the reaction with a proton $(H^{+})$,which is a hard electrophile,the attack occurs at the oxygen atom (harder center) to form the bisulfite ion $(O^{-}-S(=O)-OH)$.In the reaction with an alkylating agent like $CH_3I$ ($CH_3^{+}$ is a softer electrophile),the attack occurs at the sulfur atom (softer center) to form the methylsulfonate ion $(CH_3-S(=O)_2-O^{-})$.

The products $(A)$ and $(B)$ in the following reaction are:
