Acetylene reacts with acetic acid in presence of ion at room temperature to give

Options

A. ethyl acetate
B. acetaldehyde
C. vinyl acetate
D. methyl acetate

Explanation

To solve the problem of what product is formed when acetylene reacts with acetic acid in the presence of ions (specifically Hg2+) at room temperature, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- Acetylene (C2H2 or HC≡CH)
- Acetic acid (CH3COOH)

2. **Understand the Reaction Conditions**:
- The reaction occurs in the presence of Hg2+ ions at room temperature.

3. **Reaction Mechanism**:
- Acetylene, which contains a triple bond, can undergo an addition reaction with acetic acid.
- The presence of Hg2+ ions acts as a catalyst in this reaction.

4. **Predict the Product**:
- When acetylene reacts with acetic acid, the product formed is a vinyl compound.
- The reaction leads to the formation of vinyl acetate, which has the structure CH2=CHOOCCH3.

5. **Final Product**:
- The final product of the reaction is vinyl acetate.

6. **Select the Correct Option**:
- From the given options (Ethylacetate, Acetyldehyde, Vinylacetate, Methylacetate), the correct answer is **Vinylacetate**.

### Final Answer:
The product formed when acetylene reacts with acetic acid in the presence of Hg2+ ions at room temperature is **Vinylacetate**.
