In `C_2` molecule the double bond present has two pie bonds . Explain With Molecularorbital configuration , How ?

Explanation

To explain how the C₂ molecule has two pi bonds instead of the conventional one sigma and one pi bond, we will utilize the molecular orbital (MO) theory. Here’s a step-by-step breakdown of the solution:

### Step 1: Determine the Total Number of Electrons
The C₂ molecule consists of two carbon atoms. Each carbon atom has 6 electrons, so the total number of electrons in C₂ is:
\[ \text{Total electrons} = 2 \times 6 = 12 \]
