What is the total number of sigma and pi bonds in the following molecules?
`C_2 H_4`

Explanation

To determine the total number of sigma (σ) and pi (π) bonds in the molecule \( C_2H_4 \) (ethylene), we can follow these steps:

### Step 1: Identify the structure of \( C_2H_4 \)
- Ethylene (\( C_2H_4 \)) is an alkene, which means it contains a double bond between the two carbon atoms.
- The molecular structure can be represented as:
\[ H_2C=CH_2 \]
