Determine If a Molecule Is Polar
1. Determine the number of atoms in the molecule.
2. Count the number of hydrogen bonds that are formed between each pair of oxygen and nitrogen atoms.
3. Multiply the number of hydrogens by 2 to get the total number of electrons.
4. Divide the sum of all electron counts by the number of atoms to find the average number of electrons per atom.
5. Compare this value with the electronegativity values for the elements present.
