Ethylene on hydration gives

Options

A. Glycol
B. Ethanol
C. Ethane
D. Ethanoic acid

Answer

To solve the question "Ethylene on hydration gives," we need to understand the process of hydration of ethylene (C2H4).

### Step-by-Step Solution:

1. **Identify the Reactant**: Ethylene is an alkene with the molecular formula C2H4, which has a double bond between the two carbon atoms (CH2=CH2).

2. **Understand Hydration**: Hydration is the addition of water (H2O) to a compound. In the case of alkenes, this involves the addition of a hydrogen ion (H+) and a hydroxyl ion (OH-).

3. **Mechanism of Hydration**:
- The double bond in ethylene is reactive and can break to allow the addition of water.
- The hydrogen ion (H+) from the water molecule will attach to one of the carbon atoms, and the hydroxyl ion (OH-) will attach to the other carbon atom.

4. **Formation of Ethanol**:
- When ethylene undergoes hydration, it forms ethanol (C2H5OH). The reaction can be represented as:
\[ \text{C2H4} + \text{H2O} \rightarrow \text{C2H5OH} \]
- This means that the product of the hydration of ethylene is ethanol.

5. **Conclusion**: Therefore, when ethylene is hydrated, it produces ethanol.

### Final Answer:
Ethylene on hydration gives **ethanol (C2H5OH)**.
