Wax is ester of fatty acid with

Options

A. Long chain dihydric alcohol
B. Trihydric alcohol
C. Long chain monohydric alcohol
D. Short chain monohydric alcohol.

Answer

### Step-by-Step Solution:

1. **Understanding Wax**:
- Wax is a type of lipid that is characterized by its structure and properties. It is typically solid at room temperature and is insoluble in water.

2. **Composition of Wax**:
- Wax is formed from the esterification of a long-chain fatty acid and a long-chain alcohol.

3. **Identifying the Components**:
- The fatty acid involved in wax formation is a long-chain fatty acid.
- The alcohol that combines with the fatty acid to form wax is a long-chain monohydric alcohol (meaning it has one hydroxyl group).

4. **Ester Formation**:
- The reaction between the fatty acid and the alcohol results in the formation of an ester bond. This occurs through a condensation reaction where water is released.

5. **Properties of Wax**:
- Waxes are typically solid at room temperature, provide protection to surfaces, and are water-resistant. They are not easily hydrolyzed compared to other fats.

6. **Conclusion**:
- Therefore, the correct answer to the question "Wax is an ester of fatty acid with" is "long-chain monohydric alcohol".
