Question

Which of the following compounds will not give haloform reaction? (A) α-Phenyl ethanol (B) Acetophenone (C) Ethyl bromide (D) ( MeCO )2 O

Tardigrade Admin · Accepted Answer

In (b), (PhCOMe) contains (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

In (d), (MeCO) 22 O is an anhydride and does not give Iodoform test.
