Conversion of Acetylene into benzene

Explanation

To convert acetylene (C2H2) into benzene (C6H6), we can follow these steps:

### Step 1: Understand the structure of acetylene
Acetylene is a simple alkyne with the formula C2H2, which has a triple bond between the two carbon atoms. The structure can be represented as:
\[ \text{CH} \equiv \text{CH} \]

### Step 2: Combine three acetylene molecules
To form benzene, we need to combine three acetylene molecules. This can be visualized as:
