Which of the following would be produced when acetylene reacts with HCl ?

Options

A. `CH_(3)CH_(2)Cl`
B. `CH_(3)CHCl_(2)`
C. CH(Cl) = CH(Cl)
D. `CH_(2) = CH-Cl`

Answer

To solve the question regarding the reaction of acetylene with HCl, we need to follow a systematic approach:

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactants in this scenario are acetylene (C₂H₂) and hydrochloric acid (HCl).

2. **Understand the Reaction Type**: Acetylene is an alkyne, and it can undergo an addition reaction with HCl. In this reaction, HCl will add across the triple bond of acetylene.

3. **Determine the Product Formation**: When HCl adds to acetylene, it will first form vinyl chloride (C₂H₃Cl) through the addition of H and Cl across the triple bond.

4. **Consider Further Reactions**: Vinyl chloride can further react with another molecule of HCl to form 1,1-dichloroethane (C₂H₄Cl₂).

5. **Summarize the Products**: Therefore, the primary products of the reaction of acetylene with HCl are:
- Vinyl chloride (C₂H₃Cl)
- 1,1-Dichloroethane (C₂H₄Cl₂)

### Final Answer:
When acetylene reacts with HCl, the products formed are vinyl chloride (C₂H₃Cl) and 1,1-dichloroethane (C₂H₄Cl₂).
