Choose the incorrect statement.
- A \(\mathrm{m}\) - Cresol is a weaker acid than Phenol.
- B Acetylation of Salicylic acid produces 2-Acetoxybenzoic acid.
- C Phenol on heating with Conc. \(\mathrm{H}_2 \mathrm{SO}_4\) yields sulphanilic acid.
- D Acidic nature of Phenol is due to -I effect of oxygen of the hydroxyl group.
Answer & Solution
Correct Answer
(C) Phenol on heating with Conc. \(\mathrm{H}_2 \mathrm{SO}_4\) yields sulphanilic acid.
Step-by-step Solution
Detailed explanation
(1) Correct: m-Cresol has a \(-CH_3\) group (\(+I\) effect) which destabilizes the phenoxide ion \(\to\) weaker acid than phenol. (2) Correct: Acetylation of salicylic acid (2-hydroxybenzoic acid) with acetic anhydride gives 2-acetoxybenzoic acid (aspirin). (3) Incorrect: Phenol…

- Two statements, one Assertion and the other Reason, are given. Choose the correct option.
Assertion: During the electrolysis of aqueous \(\mathrm{NaCl}, \mathrm{Cl}_2\) is liberated at the anode in preference to \(\mathrm{O}_2\) and water gets reduced to \(\mathrm{H}_2\) at cathode.
Reason: The reaction at Anode with lower oxidation potential is not preferred due to over potential of Oxygen.COMEDK 2025 Medium
