Vedclass · Answer

(D) The iodoform test is given by compounds containing the $CH_3CO-$ group or the $CH_3CH(OH)-$ group.$1$. $ICH_2COCH_2CH_3$ contains the $CH_3CO-$ group (after considering the reaction conditions,it acts as a methyl ketone derivative),which reacts with $I_2/NaOH$ to form $CHI_3$ (yellow precipitate).$2$. $CH_3CH(OH)CH_2CH_3$ is a secondary alcohol with a $CH_3CH(OH)-$ group,which is oxidized to a methyl ketone and then undergoes the iodoform reaction to give $CHI_3$ (yellow precipitate).Therefore,both $(a)$ and $(c)$ give a yellow precipitate.

Which of the following will give a yellow precipitate with $I_2/NaOH$?
