Which of the following compounds will not give haloform reaction?A. a.alpha-Phenyl ethanolB. b.AcetophenoneC. c.Ethyl bromideD. d.`(MeCO)_(2)O`

Answer» Correct Answer - D
In `(a), (Me-underset(Ph)underset(|)overset(alpha)(CH)-OH)` contains `(Meunderset(|)(C)H-OH)` group , so it will give iodoform test.
In `(b), (PhCOMe)` sontains `(MeCO-)` group, so it will give iodoform test.
In `(c ) C_(2)H_(5)Br` under basic condition in iodoform test first is converted into `(C_(2)H_(5)OH)`, which contains `(Meunderset(|)(C )HOH)` group. So it will give iodoform test.
In `(d), (MeCO)_(2)O` is an anhydride and does not give Iodoform test. So the answer is `(d)`.
