Polarity

What does it mean to have polar bonds?

It means that there is a difference in electronegativity between the two atoms the bond is connecting.

Polar bonds are when there is a difference in electronegativity between two atoms sharing a pair of electrons. The more electronegative atom pulls the electrons slightly closer, resulting in polarity.

A polar bond will also result in a dipole (which can be both within a molecule, and between molecules). This dipole means one of the atoms has a partial negative charge and the other has a partial positive charge, making it polar.

To have a polar bond, it means that the electrons forming that bond are unequally distributed.

polar binds are observed when there is a dipole moment within a molecule. You can determine dipole moments by comparing the levels of electronegativity of the atoms. The atoms with higher electronegativity will have a stronger pull of electrons, thus causing a dipole moment.

A polar bond is when the bonded atoms have different electronegativities; this causes uneven electron distribution, and makes it "polar."

A bond that is polar has atoms with a difference in electronegativity, where one atom is slightly more positive and the other is slightly more negative. This causes an unequal distribution of e- as the more electronegative atom has a greater pull on the electrons.
