Question

A diatomic molecule has a dipole moment of $1.2D$. If the bond distance is $1.0\mathring{A}$. What fraction of an electronic charge (in %) exists on each atom?

Answer 1

Partial charge$=\frac{Dipolemoment}{Bonddistance}=\frac{1.2\times {10}^{-18}}{4.8\times {10}^{-8}}=1.2\times {10}^{-10}esu$
The fraction of an electronic charge is
$=\frac{1.2\times {10}^{-10}}{4.8\times {10}^{-10}}=0.25$ or $25$%
