Question

Which one of the following processes does not occur during formation of $CHCl_{3}$ from $C_{2}H_{5}OH$ and bleaching powder.

• A. Hydrolysis
• B. Oxidation
• C. Reduction
• D. Chlorination

Answer 1

Answer: (C)

Reduction

Answer 2

$CaOCl_{2} + H_{2}O\overset{\quad\text{Hydrolysis}\quad}{\rightarrow}Ca(OH)_{2} + Cl_{2}$

$CH_{3}CH_{2}OH + Cl_{2}\overset{\quad\text{Oxidation}\quad}{\rightarrow}CH_{3}CHO + 2HCl$

$CH_{3}CHO + 3Cl_{2}\overset{\quad\text{Chlorination}\quad}{\rightarrow}CCl_{3}CHO + 3HCl$

$\begin{matrix} CCl_{3}CHO \\ CCl_{3}CHO \end{matrix} + Ca\begin{matrix} OH \\ OH \end{matrix} \rightarrow \underset{\text{Chloroform}}{2CHCl_{3}}\underset{\text{Calcium fomate}}{+ \begin{matrix} HCOO \\ HCOO \end{matrix}Ca}$
