Vedclass · Answer

(D) The starting material is benzenesulfonic acid. $1$. Reaction with $\Delta / H_3O^+$ (desulfonation) gives $B$ which is benzene $(C_6H_6)$. $2$. Reaction with $1. 	ext{Fused } NaOH, 2. H^+$ gives $A$ which is phenol $(C_6H_5OH)$. $3$. We need to convert benzene $(B)$ to phenol $(A)$. Option $A$: Benzene $\xrightarrow{Cl_2/AlCl_3}$ Chlorobenzene $\xrightarrow{Mg/THF}$ Phenylmagnesium chloride $\xrightarrow{O_2/H^+}$ Phenol. This is correct. Option $B$: Benzene $\xrightarrow{HNO_3/H_2SO_4}$ Nitrobenzene $\xrightarrow{Sn/HCl}$ Aniline $\xrightarrow{NaNO_2/HCl}$ Benzenediazonium chloride $\xrightarrow{	ext{Steam}}$ Phenol. This is correct. Option $C$: Benzene $\xrightarrow{CH_3-CH=CH_2/H^+}$ Cumene $\xrightarrow{O_2/hv}$ Cumene hydroperoxide $\xrightarrow{H^+}$ Phenol. This is correct. Since all sequences lead to the formation of phenol from benzene,the correct option is $D$.
