During formation of `CHCl_(3)` from `C_(2)H_(5)OH` and bleaching power, which one of the following does not occur

Options

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

Answer

To solve the question regarding the formation of chloroform (CHCl₃) from ethanol (C₂H₅OH) and bleaching powder, we can break down the process into several steps.

### Step 1: Understanding the Reactants
Ethanol (C₂H₅OH) is an alcohol, and bleaching powder (Ca(OCl)₂) is a source of chlorine. The reaction involves the chlorination of ethanol to form chloroform.

**Hint:** Identify the reactants and their roles in the reaction.

### Step 2: Oxidation of Ethanol
The first step in the reaction is the oxidation of ethanol. Ethanol (C₂H₅OH) is oxidized to acetaldehyde (CH₃CHO) in the presence of bleaching powder.

\[ \text{C}_2\text{H}_5\text{OH} \rightarrow \text{CH}_3\text{CHO} + \text{H}_2\text{O} \]

**Hint:** Recognize that oxidation involves the loss of hydrogen or the gain of oxygen.

### Step 3: Chlorination of Acetaldehyde
Next, acetaldehyde (CH₃CHO) undergoes chlorination. In this step, acetaldehyde reacts with chlorine (from bleaching powder) to form chloroform (CHCl₃) and hydrochloric acid (HCl).

\[ \text{CH}_3\text{CHO} + 3\text{Cl}_2 \rightarrow \text{CHCl}_3 + 3\text{HCl} \]

**Hint:** Chlorination involves replacing hydrogen atoms with chlorine atoms.

### Step 4: Hydrolysis
The chloroform formed can undergo hydrolysis in the presence of calcium hydroxide (Ca(OH)₂) to yield chloroform and calcium carbonate.

\[ 2\text{CCl}_3\text{CHO} + \text{Ca(OH)}_2 \rightarrow 2\text{CHCl}_3 + \text{CaCO}_3 \]

**Hint:** Hydrolysis involves the reaction of a compound with water, leading to the formation of new products.

### Step 5: Identifying the Process that Does Not Occur
In the entire process of forming chloroform from ethanol and bleaching powder, we observe oxidation, chlorination, and hydrolysis. However, there is no reduction step involved in this reaction.

**Conclusion:** The process that does not occur during the formation of CHCl₃ from C₂H₅OH and bleaching powder is reduction.

### Final Answer
The correct option is **C** (Reduction does not occur).
