But the assumption of no polarity of C-H bond gives zero dipole moment of C-H bond, so only C-X bonds have vectors of displacement.

Why would you assume C-H bond has no polarity?

For easier guess. If I didn't assume it in the phenantrene problem, too I think that it would be much more complex to prove.

Well it seems to be a very poor assumption. The dipole moment of chloromethane (1.9 D) is almost twice that of chloroform (1.04 D).  Dichloromethane is somewhere in the middle (1.6 D).

I agree with what you say, I calculate as it is a bit difficult  >:D

I see. Well, that question (which has bigger dipole moment CHX3 or CH3X) was in International Mendeleev Olympiad, and the answer was that they are equal, apparently wrong.
