Oils and fats are esters of higher fatty acids with :

Options

A. Ethanol
B. Glycol
C. Glycerol
D. Methanol

Explanation

**Step-by-Step Solution:**

1. **Understanding the Components**: Oils and fats are classified as lipids. They are primarily made up of esters, which are formed from the reaction between an alcohol and a carboxylic acid.

2. **Identifying the Alcohol**: In the case of oils and fats, the alcohol involved is glycerol. Glycerol is a triol, meaning it has three hydroxyl (–OH) groups.

3. **Identifying the Fatty Acids**: The fatty acids are long-chain carboxylic acids that react with glycerol. Each fatty acid has a carboxyl group (–COOH) at one end.

4. **Formation of Triglycerides**: When glycerol reacts with three fatty acids, it undergoes a condensation reaction where three molecules of water (H2O) are removed. This process results in the formation of a triglyceride, which is the chemical name for fats and oils.

5. **Chemical Structure**: The general structure of a triglyceride can be represented as:
- Glycerol backbone (C3H8O3) + 3 fatty acids (R1COOH, R2COOH, R3COOH) → Triglyceride + 3 H2O

6. **Conclusion**: Therefore, the correct answer to the question is that oils and fats are esters of higher fatty acids with glycerol.

**Final Answer**: Oils and fats are esters of higher fatty acids with glycerol.
