ANTIBONDING Meaning and
Definition
-
Antibonding refers to a molecular electronic state, orbital, or energy level that possesses a relatively higher energy than the corresponding bonding counterpart. In chemistry, bonding occurs when two atoms come together to form a stable molecule, typically through the sharing or transfer of electrons. This process creates a lower-energy molecular orbital in which the electrons are located. However, in contrast, an antibonding orbital results in a higher-energy state, where the electrons are more likely to be found outside the region between the two atoms.
Antibonding orbitals are denoted by adding an asterisk (*) to the corresponding bonding orbital. When two atoms form a chemical bond, the combination of the bonding and antibonding orbitals creates a molecular orbital diagram. In this diagram, the bonding orbital, which promotes electron density between the atoms, is represented lower in energy, while the antibonding orbital is depicted higher in energy.
The existence of antibonding orbitals plays a crucial role in determining the stability and reactivity of molecules. When antibonding orbitals are populated with electrons, they weaken or even break the chemical bond, leading to a decrease in the stability of the molecule or making it more susceptible to reaction. As a result, antibonding interactions are often involved in chemical reactions, particularly those that involve breaking or forming new bonds.
Overall, the concept of antibonding is vital for understanding the electronic structure and reactivity of molecules. By understanding how electrons are distributed between bonding and antibonding orbitals, chemists can gain insights into the stability, reactivity, and properties of various compounds.

Etymology of ANTIBONDING
The word "antibonding" is derived from the combination of "anti-" and "bonding". "Anti-" is a prefix of Greek origin, meaning "against" or "opposite". "Bonding" refers to the formation of chemical bonds. In the context of chemical bonding theory, specifically molecular orbital theory, the term "antibonding" is used to describe a molecular orbital that is formed when two atomic orbitals combine out of phase with each other, resulting in a higher energy level and reduced electron density between the nuclei.
