Vedclass · Answer

(C) When chlorobenzene is fused with solid $NaOH$ at high temperature $(623 \ K)$ and high pressure $(300 \ atm)$,it undergoes nucleophilic substitution to form sodium phenoxide.Sodium phenoxide on subsequent acidification (hydrolysis) yields phenol.The reaction is as follows:$C_6H_5Cl + 2NaOH \xrightarrow{623 \ K, 300 \ atm} C_6H_5ONa + NaCl + H_2O$$C_6H_5ONa + H^+ \rightarrow C_6H_5OH + Na^+$Thus,the final product is phenol.
