Polarity watch

1. Why? Shouldn't the dipole moment be zero here?

because the carbon atom is tetrahedral. It is misldading when you see a two dimensional structure, but you should try to think in three dimensions.

If you think of the dipole moments as a vector, they will cancel out if you add them all up. However, as the vectors to differing atoms are of different magnitude, they won't cancel out, leaving you with a net dipole moment.

Thanks a bunch!

So whenever the geometry of the molecule is tetrahedral ( 4 bonding pairs, 0 lone pairs), the dipole moment is not equal to zero right?

If there are 1, 2 or 3 heteroatoms attached. If all attachments to the carbon are the same it is non-polar
