Iodoform can be prepared from all except

Question

Iodoform can be prepared from all except (A) ethyl methyl ketone (B) isopropyl alcohol (C) 3-methyl-2-butanone (D) isobutyl alcohol

Tardigrade Admin · Accepted Answer

Iodoform reaction is given by alcohols and ketones containing

C H_{3} - O H ∣ C H - an d C H_{3} - C ∣∣ O -

groups, respectively
Thus, among-the given compounds, isobutyl alcohol does not contain

C H_{3} - O H ∣ C H - g ro u p .

Hence, it does not give iodoform reaction on treatment with

L, / N a O H .

Hence, compounds (a), (b) and (c) will give iodoform while compound (d) (isobutyl alcohol) does not give any iodoform reaction.
