Chapter 4, Problem 75E

Interpretation Introduction

Interpretation: A combination of two $2\text{p}$ orbitals to form a $\sigma$ or a $\text{π}$ bond is to be shown.

Concept introduction: Sigma bond is defined as axial overlapping of atomic orbitals. This orbital overlaps along the inter-nuclear axis.

Pie bond is defined as the sideway overlapping of atomic orbitals. This orbital overlaps along the perpendicular of inter-nuclear axis

To determine: The explanation that a $\sigma$ or a $\text{π}$ bond is formed when two $2\text{p}$ orbitals are combined.
