Chapter 21, Problem 25QP

Interpretation Introduction

Interpretation:

The reason for the statement “the $\text{C-Cl}$ bond in a CFC molecule is preferentially broken by solar radiation at $250\text{ nm}$” is to be explained.

Concept introduction:

In a chemical reaction, bonds are formed and broken, and the energythat is required to break a bond in a chemical reaction is known as bond enthalpy.

The frequency of photons is given by the expression, which is as follows:

$\left(\nu \right)=\frac{\text{speed of wave}}{\text{Wavelength}}.$

Here, $\nu$ is the frequency.

The energy of a photon is as follows:

$E\text{ = h}\nu .$

Here, h is the Planck’s constant and $\nu$ is the frequency.
