In Koble.s reaction, instead of phenol, phenoxide ion is treated with carbon dioxide. Why?

Answer»

SOLUTION :Phenoxide ion is more reactive than phenol TOWARDS electrophilic substitution. The negative CHARGE on oxygen is transferred to benzene through resonance. The helps in the attachment of `CO_(2)` which is a weak electrophilie to the benzene ring FINALLY giving salicylic acid.
