Iodoform can be prepared from all except:

1. Ethyl methyl ketone
2. Isopropyl alcohol
3. 3-Methyl 2-butanone
4. Isobutyl alcohol

Correct answer: Isobutyl alcohol

Solution

Isobutyl alcohol cannot be converted to iodoform because it lacks the necessary structural features, specifically a methyl ketone group, which is required for the iodoform reaction to occur.
