Answer = NO3- ( nitrate ) is Polar What is polar and non-polar? The overall dipole moment of a molecule may be approximated as a vector sum of bond dipole moments.As a vector sum it depends on the relative orientation of the bonds, so that from the dipole moment information can be deduced about the molecular geometry.. For example, the zero dipole of CO 2 implies that the two C=O bond dipole moments cancel so that the molecule must be linear. If so, then you can immediately eliminate all of the ions because they are not polar since their electronegativity difference is too strong (> or = 2). The reason
