Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Percentage ionic character $=\frac{\text{Observed dipole moment}}{\text{Theoretical dipole moment}}\times 100$
Theoretical dipole moment of a 100% ionic character
$=\mathrm{e}\times \mathrm{d}=(1.6\times 10^{-19}\mathrm{C})\times (\text{1.41}\times \text{1}{\text{0}}^{-10}\mathrm{m})$
$=2.256\times 10^{-29}$

% ionic character $=\frac{2.6\times {10}^{-30}}{2.256\times 6\times {10}^{-29}}\times 100=11.5\%$
