Aim: To examine the distribution of charge (symmetry) in a molecule to determine polarity.
Molecule Polarity
Jan 91:09 PM
In chemistry, polarity refers to a separation of electric charge in a molecule, creating a dipole.
Diplole: when the more E.N. atom has a "partial" negative charge FROM pulling the electrons towards itself away from less E.N. atom.

NONPOLAR MOLECULE: a molecule with even charge distribution. These molecules are symmetrical.

POLAR MOLECULE: a molecule with uneven charge distribution. These molecules are asymmetrical.

CHECKING FOR SYMMETRYA polar covalent bond shares e- unequally and will cause a dipole. You must examine the symmetry of the molecule to determine if it is polar or nonpolar.
