Question

Chlorobenzene on fusing with solid $NaOH$ (at 623 K and 320 atm pressure) gives:

• A. benzene
• B. benzoic acid
• C. phenol
• D. benzene chloride

Answer 1

The correct option is C phenol

This is a nucleophilic substitution reaction of chlorobenzene, hydroxide ion replaces chlorine ion from chlorobenzene, and phenol forms as the product.

This reaction required high pressure and temperature since chlorobenzene does not undergo nucleophilic substitution reactions easily.

Option C is correct.
