Polarity

[Bianca Barcelo 4I]

What does it mean to have polar bonds?

[Lauryn Shinno 2H]

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

[Irene Zhou 1E]

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.

[Esha Harwalkar 3F]

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.

[Jacqueline Duong 1H]

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

[Andreana Vetus 1A]

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.

[Zachary Menz 1D]

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

[David Zhang 1B]

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.
