`KMnO_4` will oxidised acetylene to

Options

A. Ethylene glycol
B. Ethyl alcohol
C. Oxalic acid
D. Acetic acid

Explanation

To solve the question of what KMnO4 will oxidize acetylene to, we can follow these steps:

### Step 1: Identify the structure of acetylene
Acetylene is represented by the chemical formula C2H2. It has a triple bond between the two carbon atoms, which can be depicted as H-C≡C-H.

### Step 2: Understand the oxidation process
KMnO4 (potassium permanganate) is a strong oxidizing agent. When it reacts with alkynes like acetylene, it can lead to the formation of carboxylic acids.

### Step 3: Predict the product of oxidation
When acetylene (C2H2) is oxidized by KMnO4, the triple bond is broken, and the molecule is converted into a carboxylic acid. Specifically, acetylene will be oxidized to oxalic acid (H2C2O4).

### Step 4: Write the chemical reaction
The oxidation reaction can be summarized as:
\[ \text{C}_2\text{H}_2 + \text{KMnO}_4 \rightarrow \text{H}_2\text{C}_2\text{O}_4 + \text{other products} \]

### Step 5: Conclude the answer
The final product of the oxidation of acetylene by KMnO4 is oxalic acid, which has the formula H2C2O4.

### Final Answer
KMnO4 will oxidize acetylene to oxalic acid (H2C2O4).
