Vedclass · Answer

(C) The iodoform test is given by compounds containing the $CH_3CO-$ group or compounds that can be oxidized to this group (like ethanol or secondary alcohols with a methyl group). Isobutanal is $(CH_3)_2CHCHO$. It does not contain the $CH_3CO-$ group,so it does not give the iodoform test. The reason provided is incorrect because isobutanal does have an $\alpha$-hydrogen atom (the hydrogen attached to the carbon adjacent to the carbonyl group). Therefore,the Assertion is correct,but the Reason is incorrect.

Assertion : Isobutanal does not give iodoform test.
Reason : It does not have $\alpha - $ hydrogen.
