Which of the following compounds will give a yellow precipitate with iodine alkali?

Options

A. 2-Hydroxypropane
B. Acetophenone
C. Methyl acetate
D. Acetamide.

Answer

A, B

Explanation

`{:(underset((A))underset("2-Hydroxypropane")(CH_(3)-overset("OH")overset("| ")"CH"-CH_(3))" "underset((B))underset("Acetophenone")(CH_(3)-overset(O)overset("||")C-C_(6)H_(5))),(underset((C))underset("Methyl acetate")(CH_(3)-overset(O)overset("||")C-OCH_(3))" "underset((D))underset("Acetamide")(CH_(3)-overset(O)overset("||")C-NH_(2))):}`
Only methyl ketone `(CH_(3)COCH_(2)R)` and methyl carbinols `(CH_(3)CH(OH)CH_(2)R)` give iodoform test. Esters and amides do not give iodoform test.
