$I_{2} / NaOH$

Vedclass · Answer

(B) Both acetaldehyde $(CH_{3}CHO)$ and acetone $(CH_{3}COCH_{3})$ contain the methyl ketone group $(CH_{3}CO-)$,which makes them undergo the iodoform reaction.When treated with iodine $(I_{2})$ in the presence of sodium hydroxide $(NaOH)$,they form a yellow precipitate of iodoform $(CHI_{3})$.Acetaldehyde reaction:$CH_{3}CHO + 3I_{2} + 4NaOH \longrightarrow CHI_{3} + HCOONa + 3NaI + 3H_{2}O$Acetone reaction:$CH_{3}COCH_{3} + 3I_{2} + 4NaOH \longrightarrow CHI_{3} + CH_{3}COONa + 3NaI + 3H_{2}O$Fehling's solution and Tollen's reagent only react with aldehydes (like acetaldehyde) and not with ketones (like acetone).

The reagent with which both acetaldehyde and acetone react is
