Chapter 9, Problem 9.13P

(a)

Interpretation Introduction

Interpretation:

The resonance integral $\beta$ for the series consisting of ethane, butadiene, hexatriene and octatetraene has to be estimated.

Concept Introduction:

$E=\frac{hc}{\lambda }$

Where,

    $\begin{array}{c}h=6.626\times {10}^{-34}Js\\ \\ m=9.1\times {10}^{-31}kg\end{array}$

$E_n$ is the energy of n^th orbital.

$n$ is the principal quantum number.

$L$ is the length of the box.
