Solution
The correct option is A propan-2-ol
- The compounds which give positive are the one with alpha-methyl groups.
- To be more precise, Ethanal(Acetaldehyde) and methyl ketones.
- Ethanal is the only aldehyde which gives a positive iodoform test. Thus, ketone and aldehyde with structure −COCH3 also show positive results.
- propan-2-ol is CH3−CH(OH)−CH3 thus it will have −COCH3 group and hence gives a positive iodoform test.
