Vedclass · Answer

(A) The iodoform test is given by compounds containing the $CH_3-CO-$ or $CH_3-CH(OH)-$ group.Ethyl acetoacetate $(CH_3-CO-CH_2-COOC_2H_5)$ contains an active methylene group between two carbonyl groups.The protons of the methylene group are much more acidic than those of the terminal methyl group.Therefore,under basic conditions,the reaction occurs at the methylene position rather than the methyl group,preventing the formation of iodoform $(CHI_3)$.
