Esters are quite soluble in

Options

A. Alcohol
B. Benzene
C. Both alcohol and benzene
D. Water

Answer

To determine the solubility of esters, we can analyze their chemical structure and the nature of the solvents mentioned.

### Step-by-Step Solution:

1. **Understanding the Structure of Esters**:
- Esters have the general formula R-CO-O-R', where R and R' are hydrocarbon chains. The presence of the carbonyl group (C=O) and the ether link (C-O) influences their solubility.

2. **Analyzing Solubility in Water**:
- Water is a polar solvent, and for a compound to be soluble in water, it typically needs to form hydrogen bonds or have a significant number of polar functional groups.
- Esters, while they have a polar carbonyl group, do not have the ability to form hydrogen bonds with water as effectively as alcohols or carboxylic acids do. Therefore, esters are generally not soluble in water.

3. **Analyzing Solubility in Alcohol**:
- Alcohols (like ethanol) are also polar solvents and can form hydrogen bonds with esters. The polar nature of alcohol allows esters to dissolve in them. Thus, esters are soluble in alcohol.

4. **Analyzing Solubility in Benzene**:
- Benzene is a non-polar solvent. Esters can dissolve in non-polar solvents due to their hydrocarbon tails (the R and R' groups). The non-polar parts of the ester can interact with benzene, allowing for solubility.

5. **Conclusion**:
- Esters are soluble in both alcohol (a polar solvent) and benzene (a non-polar solvent). Therefore, the correct answer is that esters are quite soluble in both alcohol and benzene.

### Final Answer:
Esters are quite soluble in alcohol and benzene.
