Chapter 9, Problem 9.8P

(a)

Interpretation Introduction

Interpretation:

The ground state electronic configuration of $CO$ has to be deduced.

Concept Introduction:

Electronic configuration of molecule is the arrangement of total electrons in the various molecular orbitals. Filling of electron obey Hund’s rule and Pauli’s exclusion principle.

If the energy of same symmetry molecular orbitals formed from the combination of 2s and 2p atomic orbitals are very close, then they interact and the expected order of orbital energy changes. This phenomenon is called s-p mixing,

(b)

Interpretation Introduction

Interpretation:

The ground state electronic configuration of $NO$ has to be deduced.
