• ⭕ Sigma bonds :-
• Formed by axial overlapping of atomic orbitals.
• Larger extent of overlapping.
• Sigma bonds are stronger bonds.
• During bond dissociation sigma bonds dissociate later.
• Sigma bonds exist independently.
• Free rotation of atoms along sigma bond axis is possible.

• ⭕ Pi bonds :-
• Formed by lateral overlapping of atomic orbitals.
• Less extent of overlapping.
• Pi bonds are weaker bonds.
• Pi bonds dissociate first.
• Pi bonds always co exist with sigma bonds.
• Free rotation of atoms along pi bond is restricted.
