Vedclass · Answer

(C) $KCN$ is an ionic compound,so it provides $CN^-$ ions which act as an ambident nucleophile. The carbon atom is more nucleophilic,leading to the formation of alkyl cyanide $(C_2H_5CN)$.Therefore,the reaction $C_2H_5Br + KCN \rightarrow C_2H_5NC + KBr$ does not occur as written; it should produce $C_2H_5CN$ (ethyl cyanide).$AgCN$ is covalent,so the nitrogen atom is the nucleophilic site,leading to the formation of alkyl isocyanide $(C_2H_5NC)$.$AgNO_2$ is covalent,leading to nitroalkane $(C_2H_5NO_2)$.$KNO_2$ is ionic,leading to alkyl nitrite $(C_2H_5ONO)$.
