Question

what is permanent dipole moment ?​

Answer 1

Answer:

Permanent dipoles. These occur when two atoms in a molecule have substantially different electronegativity: One atom attracts electrons more than another, becoming more negative, while the other atom becomes more positive. A molecule with a permanent dipole moment is called a polar molecule.

Answer 2

A permanent dipole moment is when the molecule is polar. The two or more atoms within the molecule must have substantially different electronegativities (one must attract electrons more than the other and becomes more negative while the other becomes positive)
