C. Tetrachloro ethylene
D. Mixture of 1,2 and 1,1-dichloro ethane

Explanation

To solve the question of what product is formed when vinyl chloride reacts with HCl, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Vinyl Chloride**:
- Vinyl chloride is an organic compound with the formula CH₂=CHCl. It consists of a vinyl group (CH₂=CH) attached to a chlorine atom.

2. **Reaction with HCl**:
- When vinyl chloride (CH₂=CHCl) reacts with HCl, the reaction involves the addition of HCl across the double bond.

3. **Electrophilic Addition Mechanism**:
- The double bond in vinyl chloride acts as a nucleophile and attacks the electrophile H⁺ from HCl. This results in the formation of a carbocation intermediate.
- The reaction can be represented as follows:
- CH₂=CHCl + HCl → CH₃-CHCl⁺ (carbocation)

4. **Formation of Carbocation**:
- The carbocation formed (CH₃-CHCl⁺) is stabilized by resonance with the chlorine atom, which has a lone pair of electrons. This stabilization is crucial for the reaction to proceed.

5. **Nucleophilic Attack by Chloride Ion**:
- The chloride ion (Cl⁻), which is generated from HCl, acts as a nucleophile and attacks the carbocation (CH₃-CHCl⁺).
- This leads to the formation of the final product.

6. **Final Product**:
- The final product of this reaction is 1,2-dichloroethane (CH₃-CHCl₂), which is a dihaloalkane.

### Conclusion:
The product formed when vinyl chloride reacts with HCl is **1,2-dichloroethane (CH₃-CHCl₂)**.
