Conversion of ethanol to ethanoic acid is a/an

Options

A. substitution reaction
B. oxidation reaction
C. addition reaction
D. rearrangement reaction

Explanation

To determine the type of reaction that converts ethanol (CH3CH2OH) to ethanoic acid (CH3COOH), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- Reactant: Ethanol (CH3CH2OH)
- Product: Ethanoic acid (CH3COOH)

2. **Analyze the Structural Changes**:
- In ethanol, there is one hydroxyl group (-OH) and two carbon atoms.
- In ethanoic acid, there is a carboxylic acid group (-COOH) which contains an additional oxygen atom compared to ethanol.

3. **Determine the Type of Reaction**:
- Since the conversion involves the addition of an oxygen atom (from the hydroxyl group to the carboxylic acid group), we need to classify the reaction.
- The addition of oxygen indicates that this reaction is an oxidation reaction.

4. **Conclusion**:
- The conversion of ethanol to ethanoic acid is an **oxidation reaction**.

### Final Answer:
The conversion of ethanol to ethanoic acid is an **oxidation reaction**.
