Vedclass · Answer

(A) The reaction of sodium benzene sulphonate with molten $NaOH$ followed by acidification is a standard industrial method for the preparation of phenol. Step $1$: Sodium benzene sulphonate reacts with $NaOH$ to form sodium phenoxide $(C_6H_5ONa)$ and sodium sulphite $(Na_2SO_3)$. Step $2$: The resulting sodium phenoxide is then subjected to acidic hydrolysis $(H^+ / H_2O)$ to yield phenol $(C_6H_5OH)$. Therefore,the correct option is $A$.

Sodium benzene sulphonate reacts with $NaOH$ and then on acidic hydrolysis,it gives
