3. If steps 1 and 2 do not apply to the molecule, then the molecule is polar. Draw the individual bond dipole

moments for each bond in the molecule by looking up the electronegativities of each pair of bonded atoms in the

molecule. A electronegativity difference of greater than 0.5 implies that a bond dipole moment should be drawn

for that bond; draw this as an arrow along the bond, with the head of the arrow pointing towards the more

electronegative atom.

4. After all the bond dipole moments are drawn, sum all of the arrows. The resultant arrow is the direction of the

dipole moment for the molecule.
