Question
Distinguish between sigma and pi bond.
Solution
| Sr.No. | sigma bond (σ) | pi bond (π) |
| 1. | The bond formed due to overlapping along the same axis (axial overlapping) is called Sigma Bond. | The bond formed due to lateral overlapping between two p-orbitals is called a pi-bond. |
| 2. | The first or the only bond between two atoms is the sigma bond. | The pi bond is always an additional bond between two atoms. |
| 3. | The extent of overlapping is greater. | The extent of overlapping is less. |
| 4. | It is a strong bond. | It is a weak bond. |
| 5. | Formation of sigma bonds involves s - s, s - p, p - p overlap, and overlap between hybrid orbitals. | Formation of pi bonds involves p - p or d - d overlap. The overlap between hybrid orbitals is not involved. |
| 6. | The bond energy is high. | The bond energy is low. |
