Chapter 14, Problem 65P

Interpretation Introduction

Interpretation:

The reason should be explained for the stretching vibration of C-H bonds occur at larger wave number.

Concept introduction:

Wave number

Wave number is the spatial frequency of a wave, measured in cycles per unit distance or radians per unit distance.

Wave number can be calculated by following formula,

$\nu =\frac{1}{2\Pi C}{\left[\frac{f(m_1+m_2)}{m_1{m}_2}\right]}^{1/2}$
