homework 4.29

in this problem there are 3 isomers of C6H4Cl2, and it asks which has the largest dipole moment. it says that the isomer with a smaller bond angle has the largest dipole moment, why is this? I thought it would be opposite.

A smaller bond angle means that it has less of a chance of canceling each other out. When the bond angles are really small they go in practically the same direction meaning that the cancellation between the two is really small compared to larger bond angles where they could partially cancel each other out.
