Question

How to calculate of dipole moment from electro negativity?

Answer 1

Dipole moment (μ) is the measure of net molecular polarity, which is the magnitude of the charge (Q) at either end of the molecular dipole times the distance( r) between the charges.

μ=Q×r

Dipole moments tell us about the charge separation in a molecule.

The larger the difference in electronegativity of bonded atoms, the larger will be the dipole moment.
