Which of the following reactions is given by both alcohol and phenol?
Correct answer: A. Esterfication
- A. Esterfication
- B. Nitrosation
- C. Amide formation
- D. Lucas reaction
Explanation
Alcohols can readily undergo esterification reactions. In the presence of an acid catalyst (such as sulfuric acid or hydrochloric acid), alcohols react with carboxylic acids to form esters. The esterification of phenol can be achieved by reacting it with a carboxylic acid and an acid catalyst. The general reaction is as follows: PhOH + RCOOH = PhOCOR + H2O In this reaction, phenol (PhOH) reacts with a carboxylic acid (RCOOH), resulting in phenol (PhOCOR) and water (H2O). The acid catalyst, such as concentrated sulfuric acid or hydrochloric acid, helps facilitate the reaction by protonating the phenol and carboxylic acids, making them more reactive.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
