Interpretation:
An energy diagram for the molecular orbitals of period 2 diatomic molecules should be drawn and the difference in ordering for B2, C2 and N2 should be compared to O2, F2 and Ne2.
Concept introduction:
MOT is more accurate theory than
(i) The molecular orbitals are formed by the linear combination of atomic orbitals. There are two type of combination (a) constructive (b) destructive interference
(ii)Molecular orbitals formed by constructive interference is known as bonding molecular orbital, and its energy is less than atomic orbital
(iii) Molecular orbital formed by destructive interference is known as anti bonding molecular orbital and its energy is greater than atomic orbital.
(iv) Electrons in molecular orbitals are filled according to Aufbau’s rule, Pauli’s Exclusion Principle, and Hund’s rule.
