Chemical Bonding & Molecular Structure

5 terms

A covalent bond formed by the head-on overlap of atomic orbitals, with electron density concentrated along the internuclear axis.

The mixing of one s and one p orbital to give two linear hybrid orbitals at 180° to each other.

The mixing of one s and two p orbitals to give three hybrid orbitals in a plane at 120° to each other.

The mixing of one s and three p orbitals to give four hybrid orbitals directed towards the corners of a tetrahedron.

Hybridisation schemes involving d orbitals that give five trigonal bipyramidal or six octahedral hybrid orbitals.
