Polarity and Dipole Moments of Square Planar Complexes

CHEM-ATHHR5

Below are sketches of four square planar complexes. In these, the green atoms are more electronegative (EN) than the blue and black atoms. The blue atoms are less EN than the black atoms. Use this information to determine which of the following statements are true.
