Re: dipole moments
Dipoles usually cancel when the dipole moment of two atoms are facing the opposite direction.

Re: dipole moments
Dipole moments cancel when there are moments facing in opposite directions, effectively canceling each other out.

Re: dipole moments
The dipoles are vectors, and when they are equal and opposite to to each other, they cancel out.

Re: dipole moments
Dipoles cancel if the molecule is completely symmetrical (like in the trans-dicloroethane example from class).

Re: dipole moments
How do you determine dipole moments? Is it just based on the atoms in the periodic table?

Re: dipole moments
Dipole moments can be figured out based on electronegativity differences, and electronegativity has a strong correlation to the atom's position on the periodic table. So, yes, @ Leslie; but it's worth it to remember that the periodic table was based on periodic trends and not the other way around.

Re: dipole moments
In a molecule, dipole moments cancel when there are two equal dipoles oriented in the opposite direction.
