What fraction of charge is present on $I$ in covalently bonded $δ + H - δ - I$ if the dipole moment of $H I$ is $0.38 D$ and the bond length is $1.61 ˚ A$ ?

The correct option is A $5$ %
$δ, c h a r g e = \frac{D i p o l e m o m e n t}{d} = \frac{0.38 \times 10^{- 18} e s u - c m}{1.61 \times 10^{- 8}} = 2.4 \times 10^{- 11} e s u$
% of charge $= \frac{2.4 \times 10^{- 11} e s u}{4.8 \times 10^{- 10} e s u} \times 100 = 5$ %
