Which of the following is na example of non-biodegradable detergent?

Options

A.
B.
C.
D. `CH_(3)-(CH_(2))_(10)-CH_(2)-OSO_(3)Na`

Explanation

To determine which of the following is an example of a non-biodegradable detergent, we will analyze the characteristics of the detergents based on their molecular structure.

### Step-by-Step Solution:

1. **Understand the Concept of Biodegradable vs. Non-Biodegradable Detergents:**
- Biodegradable detergents are those that can be broken down by microorganisms into harmless substances. They typically have a straight-chain structure.
- Non-biodegradable detergents, on the other hand, have branched carbon chains that are not easily decomposed by microbes, leading to accumulation in the environment.

2. **Examine the Given Options:**
- We will look at the structural characteristics of each option provided in the question.
- Identify whether the carbon chain is straight or branched.

3. **Analyze Each Option:**
- **Option 1:** Long straight carbon chain - This is biodegradable.
- **Option 2:** Long straight carbon chain - This is also biodegradable.
- **Option 3:** Branched carbon chain - This is non-biodegradable.
- **Option 4:** Long straight carbon chain - This is biodegradable.

4. **Identify the Correct Answer:**
- From the analysis, we see that **Option 3**, which contains a branched carbon chain, is the only non-biodegradable detergent among the options provided.

5. **Conclusion:**
- Therefore, the correct answer to the question is **Option 3**.
