(C) The preparation of chloroform $(CHCl_3)$ from ethanol $(C_2H_5OH)$ and bleaching powder $(CaOCl_2)$ involves the following steps:$1$. Oxidation: Ethanol is oxidized to acetaldehyde $(CH_3CHO)$.$2$. Chlorination: Acetaldehyde is chlorinated to form trichloroacetaldehyde $(CCl_3CHO)$.$3$. Hydrolysis: Trichloroacetaldehyde is hydrolyzed by calcium hydroxide to form chloroform $(CHCl_3)$ and calcium formate.Elimination does not occur in this reaction sequence.

Column $I$	Column $II$
$A$. $CH_3-CHBr-CD_3$ on treatment with alc. $KOH$ gives $CH_2=CH-CD_3$ as a major product.	$P$. $E1$ reaction
$B$. $Ph-CHBr-CH_3$ reacts faster than $Ph-CHBr-CD_3$.	$Q$. $E2$ reaction
$C$. $Ph-CH_2-CH_2Br$ on treatment with $C_2H_5OD / C_2H_5O^-$ gives $Ph-CD=CH_2$ as the major product.	$R$. $E1cb$ reaction
$D$. $PhCH_2CH_2Br$ and $PhCD_2CH_2Br$ react with same rate.	$S$. First order reaction

Which of the following processes does $NOT$ occur during the preparation of $CHCl_3$ from $C_2H_5OH$ and bleaching powder?
