How do you differentiatie between sigma and pi bonds ?

Explanation

To differentiate between sigma (σ) and pi (π) bonds, we can follow these steps:

### Step 1: Definition of Sigma Bond
- **Sigma Bond (σ)**: A sigma bond is formed by the head-to-head overlapping of atomic orbitals. This means that the orbitals overlap directly along the axis connecting the two nuclei.

### Step 2: Definition of Pi Bond
- **Pi Bond (π)**: A pi bond is formed by the sidewise overlapping of atomic orbitals. In this case, the orbitals overlap above and below the axis connecting the two nuclei.
