Back Bonding vs Coordinate Bonding
The difference between Back bonding and Coordinate bonding is as follows:

Coordinate Bonding |
Back Bonding |
|---|---|---|
|
Nature of Bonding |
Coordinate bonding involves the sharing of electrons between two atoms, where the electrons are donated by one atom (ligand) to another (metal ion or central atom) |
Back bonding involves the transfer of electrons from an atomic orbital of one atom to an antibonding orbital of another atom or ligand |
|
Occurrence |
Coordinate bonds commonly occur in coordination complexes, where a central metal atom is bonded to the ligands through coordinate bonds. Here, the ligands share their lone electron pairs with the metal atom |
It is common in organometallic chemistry and occurs between atoms in a compound when one atom has a lone pair of electrons and the other has empty orbitals next to it |
|
Bonding Character |
It results in a covalent bond, and the shared pair of electrons comes from the same atom (the ligand) |
It results in a partial double-bond character, and the electrons flow from the metal ion to the ligand |
|
Influence on Molecule Properties |
Coordinate bonding does not significantly impact molecule properties such as hybridization and dipole moment |
Back bonding can affect molecule properties such as hybridization and dipole moment, and it can enhance the stability of chemical compounds |
|
Stability |
Coordinate bonding contributes to the stability of coordination complexes |
Back bonding generally increases the stability of chemical compounds, as it can enhance the strength of bonds and reduce their length |

Back Bonding
Back Bonding occurs between atoms where electrons jump from the atomic orbital to the anti-bonding orbital of the acceptor ligand. Back Bonding is also known as π-Back Bonding or Back Donation. It is a type of covalent bonding where electrons from a filled atomic orbital jump to an empty or partially filled atomic orbital.
