$PhCOCH(OH)CH_{3}$

Vedclass · Answer

(A, B) The haloform reaction is given by compounds containing the $CH_{3}CO-$ group or compounds that can be oxidized to this group (like $CH_{3}CH(OH)-$ derivatives).$1$. $ICH_{2}COCH_{2}Ph$: This compound contains an $\alpha$-hydrogen at the $ICH_{2}$ position. Under basic conditions with $I_{2}$, the $ICH_{2}$ group can be further iodinated to $CI_{3}CO-$, which then undergoes cleavage to form iodoform $(CHI_{3})$.$2$. $PhCOCH(OH)CH_{3}$: This is a secondary alcohol with a $CH_{3}CH(OH)-$ group. It is oxidized by $I_{2}/KOH$ to the corresponding ketone $PhCOCOCH_{3}$, which contains the $CH_{3}CO-$ group and thus gives the haloform reaction.Therefore, both compounds $(a)$ and $(b)$ respond to the haloform reaction.

Which of the following compounds will respond to the haloform reaction with $I_{2}$ and $KOH$?
