Dipole moments

[Harjot Manku 1C]

Im having trouble understanding Dipole Moments. Can anyone explain.

A dipole moment is a measure of a molecule's polarity. Differences in electronegativity, or charge differences, result in an unsymmetrical distribution of electrons, which is shown as a net dipole moment.

A dipole is a positive charge next to an equal but opposite negative charge. A dipole moment (μ) is the magnitude of the dipole.

Dipole moments can occur between ions in an ionic bond or atoms in a covalent bond. They occur when atoms in a molecule share electrons unequally, which occurs because one atom is more electronegative than the other. The more electronegative atom pulls more tightly on the shared electrons, creating a separation of charge that results in a dipole moment.

A dipole moment ​is a measurement of the separation of two opposite electrical charges.
Watching a video might help explain it better:

1. What is dipole? Between atoms connected by a covalent bond, due to the difference in the electronegativity, atoms share electrons unevenly. The atom with a larger electronegativity attracts electron more strongly and becomes partially negative, while the atom with a smaller electronegativity attracts electrons less strongly and become partially positive. Then we call the two atoms dipoles.
2. What is dipole moment? The measure of the electrical polarity of a system of charges. The formula is μ=qd (q means the electric charges and d means the distance between the centers of positive and negative charged ions). But I don't think we will use this formula frequently in this class. The measurement of dipole moments can also indicate the molecular structures of molecules.

In addition to what has already been said, if the dipole moments around a molecule are equal (cancel each other out), the molecule is non polar. If the dipole moments are not equal (do not cancel each other out), the molecule is polar.
