Interpretation Introduction

Interpretation:

The magnitude of partial charges in the HCl molecule is to be estimated.

Concept introduction:

Dipole moment is a vector quantity directed from the positively charged end of the polar molecule to the negatively charged end.

The magnitude of dipole moment is given by the expression:

$\mu =qr$

Here, q is the magnitude of either of the charges, $\mu$ is the dipole moment, and r represents the distance between the two charges.

The relationship between meter and angstrom can be expressed as

$1\stackrel{}{\text{Å}}\text{=}\text{1}\times {\text{10}}^{-10}\text{m}$

To convert angstrom to meter, the conversion factor is $\frac{{10}^{-10}\text{m}}{1\text{ Å}}$.

The relationship between Debye and coulomb meter can be expressed as

$1\text{}\text{D}\text{}\text{}\text{=}3.36\times {10}^{-30}\text{C}\text{.m}$

To convert angstrom to meter, the conversion factor is $\frac{3.36\times {10}^{-30}\text{C}\text{.m}}{1\text{ D}}$.

The magnitude of the partial charge is

$q=\frac{\mu }{r}$
