Question

Compound A, $C_8{H}_{10}O$, 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:

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Haloform reaction mechanism starts with the disproportionation of the halogen with the presence of the hydroxide ion. This gives the halide or the hypohalite. The hydroxide abstracts the proton, producing enolate. The hypohalite also reacts with any present methyl ketones, eventually forming a haloform. The reaction is of the Nucleophilic substitution type reaction.
Haloform reaction is shown by compound having $C{H}_3-CO-,C{H}_3-CH\left(OH\right)-$ groups option (c) has this group.
