Vedclass · Answer

(B) The iodoform test is given by compounds containing the $CH_3CO-$ group or the $CH_3CH(OH)-$ group.$CH_3CH_2OH$ contains the $CH_3CH(OH)-$ group,so it gives a positive iodoform test.$CH_3OH$ (methanol) does not contain the $CH_3CO-$ or $CH_3CH(OH)-$ group,so it does not give the iodoform reaction.$CH_3CHO$ (acetaldehyde) contains the $CH_3CO-$ group,so it gives a positive iodoform test.$PhCOCH_3$ (acetophenone) contains the $CH_3CO-$ group attached to a phenyl ring,so it gives a positive iodoform test.Therefore,$CH_3OH$ is the correct answer.
