Chapter 3, Problem 3.19P

Interpretation Introduction

Interpretation:

An orbital picture of $\text{H}-\text{C}\equiv \text{N}$ similar to that in Figure 3-23 is to be drawn.

Concept introduction:

The orbitals that overlap to form the bonds in a molecule depend on the hybridization of the central atoms. End-on overlap of hybrid orbitals leads to formation of $\text{σ}$ bond, and sideways overlap leads to the formation of $\text{π}$ bond. Hydrogen has only an s orbital and does not undergo hybridization.
