Vedclass · Answer

(A) The iodoform test is given by compounds containing the $CH_3CO-$ group (methyl ketones) or the $CH_3CH(OH)-$ group (secondary alcohols with a methyl group). $Propan-2-ol$ $(CH_3CH(OH)CH_3)$ contains the $CH_3CH(OH)-$ group,which is oxidized to acetone $(CH_3COCH_3)$ by iodine and alkali,subsequently giving a yellow precipitate of iodoform $(CHI_3)$. Benzophenone $(C_6H_5COC_6H_5)$ lacks the methyl group attached to the carbonyl carbon. Methyl acetate and acetamide do not give the iodoform test under standard conditions.

Which of the following will give a yellow precipitate $(ppt.)$ with iodine and alkali?
