Vedclass · Answer

(C) The reaction sequence represents the haloform reaction for the preparation of chloroform $(CHCl_3)$:$1$. Bleaching powder reacts with water to produce chlorine gas $(X)$:$CaOCl_2 + H_2O \longrightarrow Ca(OH)_2 + Cl_2 (X)$$2$. Acetaldehyde reacts with chlorine to form chloral $(Y)$:$CH_3CHO + 3Cl_2 \longrightarrow CCl_3CHO (Y) + 3HCl$$3$. Chloral reacts with calcium hydroxide to produce chloroform:$2CCl_3CHO + Ca(OH)_2 \longrightarrow 2CHCl_3 + (HCOO)_2Ca$Thus,'$Y$' is $CCl_3CHO$ (chloral).

Given the reactions:
$CaOCl_2 + H_2O \longrightarrow Ca(OH)_2 + X$
$X + CH_3CHO \longrightarrow Y$
$Y + Ca(OH)_2 \longrightarrow CHCl_3$
What is '$Y$'?
