Which one of the following reactions gives phenol as a major product?
- A Reaction of benzene with conc. \(\mathrm{HNO}_3\) and conc. \(\mathrm{H}_2 \mathrm{SO}_4\)
- B Reaction of aniline with \(\mathrm{NaNO}_2 / \mathrm{HCl}\) in warm water
- C Reaction of benzene with hot water
- D Sodium salt of benzoic acid with soda lime reaction
Answer & Solution
Correct Answer
(B) Reaction of aniline with \(\mathrm{NaNO}_2 / \mathrm{HCl}\) in warm water
Step-by-step Solution
Detailed explanation
Step 1 Aniline treated with \(\mathrm{NaNO}_2\) and \(\mathrm{HCl}\) form benzene diazonium chloride. Step 2 Benzene diazonium chloride is hydrolysed by dilute sulphuric acid to for phenol.
