Vedclass · Answer

(D) The given reaction is a haloform reaction (specifically iodoform test).$CH_3-CH=CH-CH_2-CO-CH_3$ contains a methyl ketone group $(-COCH_3)$.Methyl ketones react with $I_2$ in the presence of $NaOH$ to form a carboxylate salt and iodoform $(CHI_3)$.This reaction is specific to methyl ketones and does not affect the double bond present in the chain.Therefore,the correct reagent is $I_2$ and $NaOH$ solution.
