Vedclass · Answer

(C) The iodoform test is given by compounds containing the $CH_3CO-$ group or the $CH_3CH(OH)-$ group.$(a)$ Acetone $(CH_3COCH_3)$ contains the $CH_3CO-$ group,so it gives a positive iodoform test.$(b)$ Isopropyl alcohol $(CH_3CH(OH)CH_3)$ contains the $CH_3CH(OH)-$ group,so it gives a positive iodoform test.$(c)$ Butan$-2-$ol $(CH_3CH(OH)CH_2CH_3)$ contains the $CH_3CH(OH)-$ group,so it gives a positive iodoform test.$(d)$ Pentan$-3-$ol $(CH_3CH_2CH(OH)CH_2CH_3)$ does not contain either the $CH_3CO-$ or $CH_3CH(OH)-$ group,so it does not give a positive iodoform test.Therefore,compounds $(a), (b),$ and $(c)$ give a positive iodoform test.
