Vedclass · Answer

(C) $2-$pentanone is a methyl ketone $(CH_3COCH_2CH_2CH_3)$,which undergoes the iodoform reaction with $I_2$ and $NaOH$ to give a yellow precipitate of iodoform $(CHI_3)$.$3-$pentanone $(CH_3CH_2COCH_2CH_3)$ does not contain a methyl ketone group and therefore does not give the iodoform test.Thus,$I_2$ and dil. $NaOH$ can be used to distinguish between them.

$2-$pentanone can be distinguished from $3-$pentanone by the reagent:
