If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

Vedclass · Answer

(B) Nitrobenzene is used as a solvent in Friedel-Craft's reaction because it is highly resistant to electrophilic substitution due to the strong electron-withdrawing $-NO_2$ group,which deactivates the benzene ring. The fusion of nitrobenzene with solid $KOH$ is a known chemical reaction that produces a mixture of $o-$ and $p-$ nitrophenols,although the yield is generally low. Both statements are factually correct,but the reason does not explain why nitrobenzene is used as a solvent in Friedel-Craft's reaction. Therefore,the correct option is $B$.

Assertion : Nitrobenzene is used as a solvent in Friedel-Craft's reaction.
Reason : Fusion of nitrobenzene with solid $KOH$ gives a low yield of a mixture of $o-$ and $p-$ nitrophenols.
