उत्तर
The conversion of phenol to salicylic acid can be accomplished by kolbe reaction.
Explanation:
Phenol reacts with NaOH to form sodium phenoxide, which then reacts with CO2 followed by acidification to give salicylic acid (2-hydroxybenzoic acid). This is known as Kolbe’s reaction and introduces a –COOH group at the ortho position.
