Which of the following are anionic detergents ?

Options

A. Sodium salts of sulphonated long chain alcohol.
B. Ester of stearic acid and polyethylene glycol
C. Quarternay ammonium salt of amine with acetateion .
D. Sodium salts of sulphonated long chain hydrocarbons.

Answer

To determine which of the following are anionic detergents, we first need to understand what anionic detergents are. Anionic detergents are typically sodium salts of sulfonated long-chain alcohols or hydrocarbons. The anionic part of the molecule is responsible for the cleaning action.

### Step-by-Step Solution:

1. **Definition of Anionic Detergents**:
- Anionic detergents are defined as sodium salts of sulfonated long-chain alcohols or hydrocarbons.

2. **Components of Anionic Detergents**:
- The key components include:
- Sodium salt
- Sulfonated long-chain alcohol or hydrocarbon

3. **Identifying Anionic Detergents**:
- Look for compounds that fit the definition above.
- For example:
- Sodium salt of sulfonated long-chain alcohol (this is an anionic detergent).
- Sodium salt of sulfonated long-chain hydrocarbons (this is also an anionic detergent).

4. **Examples**:
- If given a list of options, identify which ones are sodium salts of sulfonated long-chain alcohols or hydrocarbons.
- Disregard options that do not fit this definition, such as quaternary ammonium salts, which are not anionic detergents.

5. **Conclusion**:
- Based on the definitions and examples, the correct options that represent anionic detergents would be the sodium salts of sulfonated long-chain alcohols and hydrocarbons.

### Final Answer:
- The correct options for anionic detergents are:
- Sodium salt of sulfonated long-chain alcohol (Option 1)
- Sodium salt of sulfonated long-chain hydrocarbons (Option 4)
