$ArX + KCN$

Vedclass · Answer

(A) In aryl halides $(ArX)$,the carbon-halogen bond acquires partial double bond character due to resonance,making it resistant to nucleophilic substitution by $CN^-$. Thus,$ArX$ does not react with $KCN$ under normal conditions to form $ArCN$.$(B)$ $ArN_2^+ + CuCN 	o ArCN + N_2 + Cu^+$ (Sandmeyer reaction).$(C)$ $ArCONH_2 \xrightarrow{P_2O_5} ArCN + H_2O$ (Dehydration of amide).$(D)$ $ArCONH_2 + SOCl_2 	o ArCN + SO_2 + 2HCl$ (Dehydration of amide).
