-
Count the number of regions around the central atom. example: CF4 has four regions around the central C atom
-
Describe the nature of the regions Example: All 4 negative regions are filled with bonding electrons
-
Describe the Bond Polarity Example: The bond between C and F is polar because its made up of different atoms therefore have different electronegativities.
-
Describe the OVERALL polarity of the molecule Example: CF4 is non-polar because it has a symmetrical tetrahedral shape. Therefore there is a equal distribution of bond dipoles around the central atom thus causing the bond dipoles to cancel each other out.
