Ethyl alcohol is highly miscible with water because if forms the following bond with water

Options

A. Covalent bond
B. Ionic bond
C. Hydrogen bond
D. Dative bond

Explanation

### Step-by-Step Solution:

1. **Understanding Miscibility**:
- Miscibility refers to the ability of two substances to mix in all proportions, forming a homogeneous solution. Ethyl alcohol (C2H5OH) is known to be highly miscible with water (H2O).

2. **Identifying the Functional Groups**:
- Ethyl alcohol contains a hydroxyl group (-OH), which is responsible for its polar nature. Water is also a polar molecule due to its bent shape and the difference in electronegativity between oxygen and hydrogen.

3. **Analyzing the Types of Bonds**:
- The options given for the type of bond formed between ethyl alcohol and water are:
- Covalent bond
- Ionic bond
- Hydrogen bond
- Dative bond

4. **Examining Hydrogen Bonding**:
- Hydrogen bonding occurs when a hydrogen atom covalently bonded to a highly electronegative atom (like oxygen) experiences an attraction to another electronegative atom. In this case, the -OH group in ethyl alcohol can form hydrogen bonds with the oxygen in water.

5. **Polar Nature of the Molecules**:
- The oxygen atom in both water and the hydroxyl group of ethyl alcohol has a partial negative charge (δ-), while the hydrogen atoms have a partial positive charge (δ+). This charge separation allows for the formation of hydrogen bonds between the two molecules.

6. **Conclusion**:
- The interaction between ethyl alcohol and water through hydrogen bonding is what makes ethyl alcohol highly miscible with water. Therefore, the answer to the question is that ethyl alcohol is highly miscible with water because it forms hydrogen bonds with water.

### Final Answer:
Ethyl alcohol is highly miscible with water because it forms hydrogen bonds with water.
