      Ethyl methyl ketone can give haloform but diethyl ketone can’t.

      The reason for this is the mechanism of the reaction with I₂ (X₂)/OH⁻ that proceeds via the enol. The result of the reaction is the substitution of H adjacent to the carbonyl with the halide. In the case of the methyl ketone under basic conditions, this gives –CX₃ which is lost from the carbonyl to end up as CHX₃ (haloform).
