What are biodegradable and non-biodegradable detergents? Give one example of each class.

Explanation

### Step-by-Step Solution:

1. **Definition of Biodegradable Detergents**:
- Biodegradable detergents are those that can be broken down by microorganisms such as bacteria. They typically consist of straight hydrocarbon chain molecules, which makes them easier for bacteria to metabolize.

2. **Definition of Non-Biodegradable Detergents**:
- Non-biodegradable detergents, on the other hand, are not easily broken down by microorganisms. They usually contain branched hydrocarbon chain molecules, which are more resistant to microbial degradation.
