How will you bring about the following conversion?
Phenol to chlorobenzene
Answer
Answer
AIEquations: $\mathrm{C_{6}H_{5}OH} + \mathrm{Zn} \xrightarrow{\text{heat}} \mathrm{C_{6}H_{6}} + \mathrm{ZnO}$ $\mathrm{C_{6}H_{6}} + \mathrm{Cl_{2}} \xrightarrow{\text{anhydrous}\text{ }\mathrm{FeCl_{3}}} \mathrm{C_{6}H_{5}Cl} + \mathrm{HCl}$
Phenol to chlorobenzene: reduction with zinc dust to benzene, then chlorination.
