1)
HCl consists of one H and Cl atom separated by 0.127 nm, the bond length. The Cl atom has a partial charge of -0.177e and the H atom has a partial charge of +0.177e, where e = 1.602x10-19 C is the electron charge.
What is the dipole moment of the molecule?
2)
Now the HCl molecule is placed near a sodium ion Na+with charge +1e. As shown in the figure, the distance between the Cl and Na atoms is d = 1.6 nm.
What is the magnitude of the total force on the HCl molecule due to the Na+ ion |FHCl|?
3)
Compare your previous answer to the force on a single Cl- ion with charge -1e due to the Na+ ion 1.6 nm away.
What is the ratio of the force on the Cl- ion to the force on the HCl molecule |FCl-/FHCl|?

A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
