Vedclass · Answer

(C) The reaction of chlorobenzene with $NaOH$ at high temperature and pressure is known as the $Dow$ process. In this reaction,the primary product is sodium phenoxide $(C_6H_5ONa)$,which upon acidification gives phenol. However,a side reaction occurs where the formed phenoxide ion reacts with unreacted chlorobenzene via a nucleophilic substitution reaction to form diphenyl ether $(C_6H_5OC_6H_5)$. This side reaction reduces the overall yield of the desired phenol product.

When $C_6H_5Cl$ is heated with $NaOH$ at $300 \, ^\circ C$ under pressure,phenol is obtained. However,the yield is low because a side reaction produces ...............
