Chapter 9, Problem 9E.2DQ

Interpretation Introduction

Interpretation:

The difference between delocalization energy, $\text{π}$-electron binding energy and $\text{π}$-bond formation energy has to be stated.

Concept introduction:

The pi-molecular orbital energy level diagrams for the conjugated molecules can be drawn with the help of a set of approximations.  These approximations were suggested by Erich Huckel in 1931.  The $\text{π}$-orbitals are assumed to be made from the linear combination of $\text{p}$ orbitals.
