We’re asked to determine the approximate location of the negative pole on each of these molecules and to select and explain which has a higher dipole moment.

Remember that the dipole moment between the two elements is dependent on the electronegativity (EN), and its magnitude is related to their difference in EN.

Additionally, its direction is indicated as an arrow:

Least EN element  Most EN element


The EN values for the involved elements in both molecules are:

H = 2.2, C = 2.5, O = 3.5, F = 4.

Problem Details

Where, approximately, is the negative pole on each of these molecules?

Which molecule should have higher dipole moment, and why?

a. COF2 because it contains more F atoms.

b. COFH because the polar bonds in COF 2 nearly cancel each other out.

c. COF2 because it contains more lone pairs.
