(a)
Interpretation:
The bonding and antibonding molecular orbitals with respect to energy are to be compared.
Concept introduction:
Bonding orbital is a type of molecular orbital that strengthens the
(b)
Interpretation:
The bonding and anti-bonding molecular orbitals with respect to the presence of nodes are to be compared.
Concept introduction:
Bonding orbital is a type of molecular orbital that strengthens the chemical bond between atoms and it helps to decrease the energy of the molecule and therefore stabilizes it. Anti-bonding is a type of molecular orbital that weakens the chemical bond between atoms and it helps to increase the energy of the molecule and therefore destabilizes it. Bonding molecular orbitals are lower in energy than anti-bonding molecular orbitals.
Node is the point where the probability to find electrons is zero and the repulsive forces between electrons increase much more than the attractive forces between the electron and the nucleus of the atom.
(c)
Interpretation:
The bonding and anti-bonding molecular orbitals with respect to internuclear electron density are to be compared.
Concept introduction:
Bonding orbital is a type of molecular orbital that strengthens the chemical bond between atoms and it helps to decrease the energy of the molecule and therefore stabilizes it. Anti-bonding is a type of molecular orbital that weakens the chemical bond between atoms and it helps to increase the energy of the molecule and therefore destabilizes it. Bonding molecular orbitals are lower in energy than anti-bonding molecular orbitals.
