Vedclass · Answer

(D) The reaction $X \xrightarrow{Y} CHCl_3 + Z$ represents the haloform reaction.For a compound to undergo the haloform reaction,it must contain either a $CH_3CO-$ group or a $CH_3CH(OH)-$ group.$A$. $2$-Butanol $(CH_3CH(OH)CH_2CH_3)$ contains the $CH_3CH(OH)-$ group and $NaOCl$ provides the halogen source,so it gives the haloform reaction.$B$. Ethanol $(CH_3CH_2OH)$ contains the $CH_3CH(OH)-$ group and $CaOCl_2$ provides the halogen source,so it gives the haloform reaction.$C$. Butanone $(CH_3COCH_2CH_3)$ contains the $CH_3CO-$ group and $NaOH / Cl_2$ provides the halogen source,so it gives the haloform reaction.$D$. Ethanol $(CH_3CH_2OH)$ is a valid substrate,but $NaCl$ is not an oxidizing/halogenating agent capable of performing the haloform reaction. Therefore,this pair does not represent the reaction.
