A. `CH_(3)CHO`
B. `CH_(3)CH_(2)OH`
C. `CH_(3)COOH`
D. `CH_(3)OH`

Answer

To identify the product of the reaction between acetylene (HC≡CH) and the oxidizing agents K2Cr2O7 and H2SO4, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are:
- Acetylene (HC≡CH)
- Potassium dichromate (K2Cr2O7)
- Sulfuric acid (H2SO4)

### Step 2: Understand the Role of the Oxidizing Agent
K2Cr2O7 in the presence of H2SO4 acts as a strong oxidizing agent. This means it will facilitate the oxidation of acetylene.

### Step 3: Determine the Type of Reaction
The reaction is an oxidation reaction. Acetylene (HC≡CH) will be oxidized to a higher oxidation state compound.

### Step 4: Predict the Product
When acetylene is oxidized, it can first form an aldehyde and then further oxidize to a carboxylic acid. The expected product from the complete oxidation of acetylene is acetic acid (CH3COOH).

### Step 5: Write the Balanced Reaction
The balanced reaction can be represented as follows:
\[ 2 \, HC≡CH + 4 \, K2Cr2O7 + 6 \, H2SO4 \rightarrow 4 \, CH3COOH + 2 \, Cr2(SO4)3 + 4 \, K2SO4 + 6 \, H2O \]

### Step 6: Conclusion
The final product of the reaction is acetic acid (CH3COOH).

### Final Answer
The product of the reaction is **acetic acid (CH3COOH)**.
