Vedclass · Answer

(C) The given reaction involves the oxidation of a methyl ketone group $(-COCH_3)$ to a carboxylic acid group $(-COOH)$ while keeping the carbon-carbon double bond intact.This transformation is characteristic of the haloform reaction.When a methyl ketone is treated with $I_2$ and $NaOH$,it undergoes the iodoform reaction to form a carboxylate salt,which upon subsequent acidification yields the corresponding carboxylic acid.The reaction is:$CH_3-CH=CH-CH_2-COCH_3 \xrightarrow[(ii) 	ext{ Acidification}]{(i) I_2/NaOH} CH_3-CH=CH-CH_2-COOH + CHI_3$

Which is the most suitable reagent for the following conversion?
$CH_3-CH=CH-CH_2-CO-CH_3 \rightarrow CH_3-CH=CH-CH_2-COOH$
