Dipole moment vs dipole bond

[Abby Lam 3F]

What is the difference between dipole moment and dipole bond?

[Ria Nawathe 1C]

A dipole moment is a partial positive charge and partial negative charge within a molecule, though the molecule is as a whole electrically neutral. For example, the hydrogens in H2O have a partial positive charge and the oxygen has a partial negative charge due to the electronegativity difference between the atoms and their comparative ability to pull electrons. A dipole-dipole bond is an intermolecular force where 2 molecules that have dipoles are attracted to each other: the delta positive of one to the delta negative of the other and vice versa. Hope this helps!

I think you are asking the difference between bond dipole/dipole moments formula and dipole-dipole forces.

Dipole-Dipole Forces are intermolecular attractions between two molecules. They are the weakest bonds and all polar covalent compounds have them

The dipole moments formula measure the polarity of a chemical bond within a molecule.

The formula is mu= delta * d
- mu = bond dipole
- delta = charge
- d = distance between partial charges (bond length)

You will not need to use the formula on the MT2, but know that an increase in bond length increases the dipole moments.

Hi, a dipole moment refers to the polarity of a molecule or bond. So, if a bond has a particular positive charge on one end and a negative on the other due to differences in electronegativity (or, if induced, due to interaction with another molecule), then it has a dipole moment of a particular value (which, combined with the dipole moments of other constituent bond dipole moments in the molecule, contributes to the total molecular dipole moment). A dipole bond refers to the attraction that occurs between two separate polar molecules. For example, the positive end of one molecule of chloromethane forms a dipole bond with the negative end of another molecule of chloromethane.

Hello! A dipole moment is a measure of the polarity of a certain bond. Therefore, if we have a polar bond, then it will have a non-zero dipole moment. Of course, a polar bond arises from the unequal sharing of electrons between atoms (differences in electronegativity), so a dipole moment is also a measure of the difference in electronegativity between atoms.

Hope this helps!

This helped me thank you!
