# The dipole moment of $KCl$ is $3.336 \times 10^{-29}$ coulomb meter which indicates that it is a highly polar molecule. The inter atomic distance between $K^+$ and $Cl^{-}$ in this molecule is $2.6 \times 10^{-10}\;m$ Calculate the dipole moment of $KCl$ molecular if there were opposite charges of one fundamental unit located at each nucleus. Calculate percentage ionic character of $KCl$
$(A)\;4.1652 \times 10^{-27} \\ (B)\;4.1762 \times 10^{-29} \\(C)\;4.2345 \times 10^{-28} \\(D)\;4.1652 \times 10^{-29}$
