Vedclass · Accepted Answer

Benzene + conc. $H_2SO_4 \xrightarrow{\Delta}$ Phenol

Vedclass · Answer

(D) The preparation of phenol involves specific industrial and laboratory methods. $A$. Aniline can be converted to phenol via benzene diazonium chloride (diazotization followed by hydrolysis). This is a standard method. $B$. Cumene oxidation is the most common industrial method for producing phenol. $C$. The Dow process involves the reaction of chlorobenzene with $NaOH$ at high temperature and pressure to form sodium phenoxide,which upon acidification yields phenol. This is a standard method. $D$. Benzene reacts with concentrated $H_2SO_4$ to form benzene sulfonic acid,not phenol directly. Phenol is obtained from benzene sulfonic acid by fusion with $NaOH$ followed by acidification. Therefore,the reaction as written is incorrect.
