Sigma and PI Bond
- Sigma Bond:
(a) It is formed by the axial overlapping of atomic orbitals containing unpaired electrons.
(b) Electron intensity is concentrated along the axis of nuclei.
(c) It is primary bond and strong bond
(d) In a molecule first sigma bond is formed.
- PIE Bond:
(a) It is formed by the lateral overlap of atomic orbitals.
(b) Electron intensity is concentrated away from the inter nuclear axis.
(c) It is weaker bond.
(d) It is secondary bond.
(e) In a molecule it is formed angle Sigma bond is formed.
