Compound A, C8H10O, is found to react with NaOI (produced by reacting Y with NaOH) and yields a yellow precipitate with characteristic smell. A and Y are respectively

1. H3C–CH2–OH and I2
2. CH2–CH2–OH and I2
3. CH3–OH and I2
4. CH–CH3 and I2

Correct answer: CH–CH3 and I2

Solution

Compound A (C8H10O) reacts with NaOI to form a yellow precipitate of iodoform, indicating the presence of a methyl ketone group. Y is I2, which reacts with NaOH to produce NaOI. Thus, A is CH3–CO–CH3 (acetophenone) and Y is I2.
