Question

$Ph{CH}_{2}Br\underset{Acetone}{\overset{NaCN}{\to }}Ph{CH}_{2}CN$

Guess the product when $PhC{H}_{2}Br$ reacts with $AgCN$.

Answer 1

Here, CN substitutes -Br group and

$Ph{CH}_{2}Br\underset{Acetone}{\overset{NaCN}{\to }}Ph{CH}_{2}CN$

and in case of $AgCN$ we get,

$Ph{CH}_{2}Br\underset{Acetone}{\overset{AgCN}{\to }}Ph{CH}_{2}NC$
