Which of the following statements is not true regarding molecular orbi...
Explanation:
Molecular orbital theory is a model that describes the behavior of electrons in a molecule in terms of the combination of atomic orbitals to form molecular orbitals. Here are the explanations of each option:
a) The atomic orbitals of comparable energies combine to form molecular orbitals: This is true. When atomic orbitals of comparable energies combine, they form molecular orbitals that are delocalized over the entire molecule.
b) An atomic orbital is monocentric while a molecular orbital is polycentric: This is also true. An atomic orbital is centered on a single atom, while a molecular orbital is delocalized over the entire molecule.
c) Bonding molecular orbital has higher energy than antibonding molecular orbital: This statement is not true. In fact, the bonding molecular orbital has lower energy than the atomic orbitals from which it was formed, while the antibonding molecular orbital has higher energy than the atomic orbitals from which it was formed.
d) Molecular orbitals like atomic orbitals obey Aufbau principle for filling of electrons: This is true. Just like atomic orbitals, molecular orbitals are filled with electrons in accordance with the Aufbau principle, which states that electrons fill the lowest energy orbitals first.
In conclusion, option (c) is the statement that is not true regarding molecular orbital theory.
