VSEPR and Polarity

Postby HuyHa_2H » Sat Nov 16, 2019 5:13 pm

Just for confirmation, what do you generally look at in a VSEPR model to determine polarity of a molecule?

You can look at the symmetry of the atoms in order to determine polarity.

You look for which atoms are electronegative and see where they are placed in order to see if their dipoles cancel out or make the molecule polar.

If one atom is more electronegative than the other, there will be a dipole moment. Although the bonds are polar, the molecule will not if the shape is symmetrical causing the dipoles to cancel out.

Polar molecules are asymmetrical in electronegativity and the geometry or formation. Asymmetrical electronegativity meaning there is an atom with a partial positive charge surrounding an atom with a partial negative charge with an electronegativity difference of 0.5-1.6. Asymmetrical formation assures that the symmetry of the bonds don't cancel out the asymmetry of the electronegativity.
