Chapter 21, Problem 26QP

Interpretation Introduction

Interpretation:

The longest wavelength needed to break the $\text{C-Br}$

bond in the given reaction is to be determined and whether this compound decompose in given condition is to be predicted.

Concept introduction:

The energy required to dissociate a bond is calculated as follows:

$\text{Energy per molecule}=\frac{\text{Bond energy}}{6.022\times {10}^{23}}$

The energy of the bond is calculated as follows:

$E=\text{h}\nu$ or $\nu =\frac{E}{\text{h}}$

Here, $\text{h}$

is Planck’s constant and $\nu$

is the frequency of radiation.

The wavelength is given as follows:

$\lambda =\frac{\text{c}}{\nu }$

Here, $\text{c}$

is the speed of light.
