Question

The structure of product C, formed by the following sequence of reaction is :

\( CH _{3} COOH + SOCl _{2} \longrightarrow A \stackrel{\text { Benzene }}{ AlCl _{3}} \rightarrow B \frac{ KCN }{- OH } \rightarrow C \)

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Carboxylic acid with $SOC{l}_2$ gives acid chloride.
Acid chloride with benzene and lewis acid $\left(AlC{l}_3\right)$ undergoes Friedel craft acylation reaction. In final step, $C{N}^{-}$ undergoes nucleophilic addition reaction with keto group to form cyanohydrin.

Hence, option (d) is the correct answer.
