What is the total number of sigma and pi bonds in the following molecules?
`C_2 H_2`

Explanation

To determine the total number of sigma (σ) and pi (π) bonds in the molecule C₂H₂ (ethyne), we can follow these steps:

### Step 1: Understand the structure of C₂H₂
C₂H₂ is an alkyne, which means it contains a carbon-carbon triple bond. The structure can be represented as:
```
