Multiple Choice

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

AMethyl acetate
BAcetamide
C2-Hydroxypropane
Correct Answer
DAcetophenone
Correct Answer

Solution

Haloform reaction,

$$CH_3COR$$ is oxidized by $$NaOI$$ to form iodoform and $$RCO_2Na$$
wherein

$$C_6H_5COCH_3+NaOH+I_2\rightarrow C_6H_5CO_2Na+CHI_3$$

Methyl acetate and Acetamide will not give a yellow precipitate.
But 2-Hydroxypropane and Acetophenone will give a yellow precipitate.

The correct option is C and D.
