suppose that K and Cl atoms in the ionic compound are charge

suppose that K and Cl atoms in the ionic compound are charged +e and -e respectively. Look up the KCl bond length. Taking this to be the distance d, what is your estimate for dipole moment of KCl in debyes. How close is this to the reported value of dipole moment?

Solution

Distance between k and cl is 2.8 x 10^-10 m ,

Dipole moment = e x d = 1.6x 10^-19 x 2.8 x 10^-10 m = 4.48 x 10^-29 C-m.
