Bonding Molecular Orbitals ($BMO$)
			
			Antibonding Molecular Orbitals ($ABMO$)
			
		
		
			It is in short $BMO$. Its wave function is express by $\psi_{	ext {MO }}$.
			
			It is in short $ABMO$ its wave function is express by $\psi_{	ext {MO }}^{*}$
			
		
		
			
			Definition: They are formed by the addition of atomic orbital is known of $BMO$.

			$\psi_{\mathrm{MO}}=\psi_{\mathrm{A}}+\psi_{\mathrm{B}}$
			
			
			Definition : They are formed by the substractive effect of the atomic orbitals is known $ABMO.$
			
		
		
			Qualitative, the formation of $BMO$ can be understood in terms of the constructive of the electron waves of the combining atoms and reinforce each other.
			
			$\psi^{*}$ MO $=\psi_{	ext {A }}$ - $\psi_{	ext {B }}$ Qualitative, the formation of $ABMO$ can be under- stood in terms of the destructive interference of the electron waves of the combining atoms and cancel each other.
			
		
		
			As a result, the electron density in a $BMO$ is located between the nuclei of the bonded atoms because of which the repulsing between the nuclei is very less.
			
			In case of an $ABMO$, most of the electron density is located away from the space between the nuclei

			 
			
		
		
			The nodal plane is not present in $BMO.$
			
			There is a nodal plane (on which electron density is zero) between the nuclei.
			
		
		
			Electron placed in a $BMO$ tend to hold the nuclei together and stabilize a molecule.
			The electron placed in the $ABMO$ destabilize the molecule.
		
		
			A $BMO$ always possesses lower energy than either the atomic orbitals that have combined to from it.
			The $ABMO$ always possesses higher of energy than either of the atomic orbitals that have combined to form it
		
		
			In $BMO$, the repulsion between electron-electron is less than the attraction between electron and nuclei, So energy is less of $BMO$.
			In$ABMO$, repulsion of electron is more than the attraction between the electrons and the nuclei, which causes a not increase energy.
		
		
			BMO is stable. e.g. $\sigma$ and $\pi$ are $BMO$.
			$\mathrm{ABMO}$ is unstable. e.g. $\sigma^{*}$ and $\pi^{*}$ are $ABMO$.
