OPTION C) IS CORRECT
I HOPE IT WILL HELP YOU

Answer 2

Dear Shikhar,

◆ Answer -

(d) all above three rules - (a), (b) and (c)

◆ Explanation -

LCAO (Linear Combination of Atomic Orbitals) obeys following rules -

a) Pauli's exclusion principle -

- It states that two fermions in the same atom can't have the same 4 quantum numbers.

b) Aufbau principle -

- It states that electrons fill lower energy orbitals before higher energy orbitals in ground state of atom.

c) Hund's rule of maximum multiplicity -

- It states that for a given electron configuration, the lowest energy term is the one with the greatest value of spin multiplicity.

Hope this helped..
