Write the difference between the sigma () bond and pi () bond.
Difference between Sigma bond and Pi bond:
Sigma bond | Pi bond |
The bond formed by the coaxial overlap of the atomic orbitals is known as the sigma bond. | The bond formed by the lateral overlap of the atomic orbitals is known as the Pi bond. |
Due to the coaxial overlap of the atomic orbitals the electron density is high along the axis of the molecule. | Due to the lateral overlap of the atomic orbitals, the electron density is zero along the axis of the molecule. |
A high amount of energy is liberated due to bond formation as the extent of overlap is more. | Comparatively less energy is liberated during the pi bond formation as the extent of overlap is less. |
Sigma bonds are strong bonds | Pi bonds are weak bonds. |
Sigma bonds are formed between s-s, p-p, s-p, and hybrid orbitals | Pi bonds are formed between p-p or d-d orbitals but not between hybrid orbitals., |
