Question

The conversion, $PhCN\to PhCOC{H}_3$, can be achieved most conveniently by reaction with.

• A. $C{H}_{3}MgBr$ followed by hydrolysis
• B. $I_2$-NaOH, $C{H}_{3}I$
• C. Dil. $H_{2}S{O}_4$ followed by reaction with $C{H}_3{N}_2$
• D. LAH followed by reaction with $C{H}_{3}I$

Answer 1

The correct option is A $C{H}_{3}MgBr$ followed by hydrolysis

(Refer to Image)

So, the conversion is best suitable if it is followed by addition of $C{H}_{3}MgBr$ followed by hydrolysis.
