$CH_3COCH_2CH_2Br$

Vedclass · Answer

(B) In $CH_3COCH_2CH_2Br$,the $\alpha$-hydrogen atoms are acidic due to the electron-withdrawing effect of the carbonyl group. Upon treatment with alcoholic $KOH$,it forms a carbanion $CH_3CO\bar{C}H-CH_2Br$ which is stabilized by resonance with the carbonyl group. This stabilization facilitates the elimination reaction,making it the most reactive among the given options.

Which of the following is most reactive towards alcoholic $KOH$?
