Lauryl alcohol on treatment from the following by neutralisation froms a produt which is

Options

A. Cationic detergent
B. anionic detergent
C. Neutral detergent
D. antidepressant

Explanation

To solve the question regarding the product formed when lauryl alcohol undergoes neutralization, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Lauryl Alcohol**:
- Lauryl alcohol, also known as dodecanol, has the chemical formula CH3(CH2)10OH. This is a long-chain fatty alcohol.

2. **Reaction with Sulfuric Acid**:
- When lauryl alcohol is treated with sulfuric acid (H2SO4), it undergoes protonation and forms lauryl hydrogen sulfate. The reaction can be represented as:
\[ \text{CH}_3\text{(CH}_2)_{10}\text{OH} + \text{H}_2\text{SO}_4 \rightarrow \text{CH}_3\text{(CH}_2)_{10}\text{OSO}_3\text{H} \]
- This product is known as lauryl hydrogen sulfate.

3. **Neutralization Reaction**:
- The lauryl hydrogen sulfate then reacts with a base (for example, sodium hydroxide, NaOH) in a neutralization reaction:
\[ \text{CH}_3\text{(CH}_2)_{10}\text{OSO}_3\text{H} + \text{NaOH} \rightarrow \text{CH}_3\text{(CH}_2)_{10}\text{OSO}_3\text{Na} + \text{H}_2\text{O} \]
- This reaction produces sodium lauryl sulfate and water.

4. **Final Product**:
- The final product formed from the neutralization of lauryl alcohol is sodium lauryl sulfate (CH3(CH2)10OSO3Na), which is a well-known anionic detergent.

### Conclusion:
The product formed from the neutralization of lauryl alcohol is **sodium lauryl sulfate**.
