Options

A. ethanoyl chloride
B. ethylene chlorohydrin
C. ethylene chloride
D. ethylene glycol

Explanation

To solve the question, "Ethene gas is bubbled through water saturated with chlorine. The major product formed will be," we can follow these steps:

### Step 1: Identify the Reactants
- We have ethene gas (C2H4), which is represented as CH2=CH2.
- We also have water that is saturated with chlorine, which means it contains hypochlorous acid (HOCl) because chlorine reacts with water to form this acid.

### Step 2: Understand the Reaction Mechanism
- When ethene is bubbled through the water saturated with chlorine, the hypochlorous acid (HOCl) will react with the double bond of ethene.
- The double bond in ethene is a site of high electron density, making it susceptible to electrophilic attack.

### Step 3: Electrophilic Addition Reaction
- The reaction involves the addition of HOCl across the double bond of ethene.
- The reaction can be visualized as follows:
- The double bond (C=C) opens up to allow the addition of the HOCl.
- One part of the HOCl adds to one carbon atom, and the other part adds to the other carbon atom.

### Step 4: Identify the Product
- The product formed from this reaction is ethylene chlorohydrin.
- The structure of ethylene chlorohydrin can be represented as CH2OH-CH2Cl.
- This means that one carbon atom has a hydroxyl group (-OH) and the other has a chlorine atom (-Cl) attached.

### Step 5: Conclusion
- Thus, the major product formed when ethene gas is bubbled through water saturated with chlorine is ethylene chlorohydrin (CH2OH-CH2Cl).

### Final Answer
The major product formed will be **ethylene chlorohydrin**.
