Pi Bond
Chemical Bonding & Molecular Structure
kJ/mol
A covalent bond formed by the sideways overlap of parallel p orbitals, with electron density above and below the internuclear axis.
Polar Covalent Bond
Chemical Bonding & Molecular Structure
D
A covalent bond in which the shared electrons are unequally distributed because the bonded atoms differ in electronegativity.
δ⁺A—Bδ⁻
Polarisability
