Chapter 15, Problem 15.51E

Interpretation Introduction

Interpretation:

The Hückel determinant for naphthalene, ${\text{C}}_{10}{\text{H}}_8$, is to be stated.

Concept introduction:

According to the Hückel approximation of the $\pi$ molecular orbitals, the sigma bonds and pi bonds are considered separately. Also, it is assumed that $\pi$ molecular orbitals are the linear combinations of $2p$ orbitals from the different carbon atoms. From the linear variation theory, the energies of the $\pi$ molecular orbitals can be determined by using the secular determinant.
