Question

what is koble's reaction

Answer 1

When phenol is treated with sodium hydroxide, phenoxide ion is generated. The phenoxide ion generated is more reactive than phenol towards electrophilic aromatic substitution reaction. Hence it undergoes electrophilic substitution reaction with carbon dioxide which is a weak electrophile. Ortho-hydroxybenzoic acid (salicylic acid) is formed as the major product. This reaction is popularly known as Kolbe’s reaction. It is named after the scientist Hermann Kolbe.

Answer 2

Kobles reaction is the reaction to convert phenol into hydroxide....
