Chapter 10, Problem 10.108CHP

Interpretation Introduction

Interpretation:

The explanation for smaller dipole moment in Fluoromethane when compared to Chloromethane has to be given.

Concept Introduction:

Dipole moment:

Dipole moment is quantity that is used to measure net molecular polarity.  It is represented as $\text{μ,}$ and can be defined as magnitude of charge Q present at either end of specific dipole times the distance r seen between the charges.  The dipole moment is expressed using formula,

$\text{μ=Q×r}$

Debye is the unit of dipole moment.

One Debye is equal to $\text{3}{\text{.336×10}}^{\text{-30}}\text{coulomb}\text{meters}\left(\text{c}\text{.m}\right)$ in S.I units.
