Which of the following statements regarding chemical properties of acetophenone are wrong……
(1) It is reduced to methyl phenyl carbinol by sodium and ethanol
(2) It is oxidised to benzoic acid with acidified KMnO₄
(3) It does not undergo iodoform electrophilic substitution like nitration at meta position
(4) It does not undergo iodoform reaction with iodine and alkali

Question

Quizplus · Accepted Answer

Statement (3) is incorrect because acetophenone can undergo electrophilic substitution reactions like nitration, but it does not preferentially occur at the meta position; rather, it occurs at the ortho and para positions due to the electron-donating effect of the carbonyl group. Statement (4) is incorrect because acetophenone does undergo the iodoform reaction due to the presence of a methyl group adjacent to the carbonyl group, which is a requirement for the iodoform test.
