How are bonding and antibonding molecular orbitals formed from a given pair of atomic orbitals? Compare these molecular orbitals with each other in terms of their energy?
Answers
Explanation:
Bonding and antibonding orbitals form when atoms combine into molecules. ... Therefore each original atomic orbital of the isolated atoms (for example, the ground state energy level, 1s) splits into two molecular orbitals belonging to the pair, one lower in energy than the original atomic level and one higher.
When two atomic orbitals combine to form a pair of molecular orbitals, the bonding molecular orbital is stabilized about as much as the antibonding molecular orbital is destabilized. The interaction between atomic orbitals is greatest when they have the same energy.
Answer:
electrons in bonding orbitals stabilize the molecule because they are between the nuclei .they also have lower energies because they are closer to the nuclei...Antibonding pi orbitals have higher energy levels and less electron density between the nuclei.
