JEE Main 2026 Chemistry question

Chemistry Organic Chemistry - Some Basic Principles and Techniques JEE Main 2026

The correct order of the rate of the reaction for the following reaction with respect to nucleophiles is: CH_3Br + Nu^{\Theta} \to CH_3Nu + Br^{\Theta}

(1)PhO^- > {}^-OH > CH_3COO^- > ClO_4^-
(2)ClO_4^- > CH_3COO^- > {}^-OH > PhO^-
(3)CH_3COO^- > PhO^- > {}^-OH > ClO_4^-
(4)^-OH > PhO^- > CH_3COO^- > ClO_4^-Correct

Answer: (4)

Solution

Nucleophilicity order is reverse of stability/basicity order: OH^- > PhO^- > CH_3COO^- > ClO_4^-.
