Chemistry - CHEMICAL BONDING Question with Solution | TestHub
As its name implies, MOLECULAR ORBITAL THEORY allocates electrons to molecular orbitals similar in many respects to atomic orbitals, but each containing two or more nuclei. To derive the ground state of the molecule, the electrons are placed in the available molecular orbitals, beginning with the orbital of lowest energy; each molecular orbital can accommodate a maximum of two electrons, provided their spins are opposed (Pauli's principle extended to molecules); and by filling as few orbitals as possible, and those of the lowest energy possible, we arrive at the electronic ground state.
If each atomic orbital and molecular orbital can hold maximum 3 electrons. Then select CORRECT statement(s) :-
Options:(select one or more)
Answer:
Solution:
If each orbital can hold maximum 3 electrons, then oxygen atom configuration becomes:
O = 1s³ 2s³ 2p², so statement (A) is correct.
For O₂, total electrons = 16; in MO filling, bonding electrons = 10, so statement (B) is correct.
In O₂, antibonding electrons are 6 (not 8), so statement (C) is incorrect.
Therefore, statement (D) is also incorrect.
