Which isomer of the square planar complex $[Pt (NH X_{3}) X_{2} Cl X_{2}]$ has a non-zero dipole moment?

Acis isomer only
Bboth isomers equally
Ctrans isomer only
Dneither isomer

Answer: A

In the trans isomer, identical ligands are opposite each other and the dipoles cancel. In the cis isomer, the Pt-Cl dipoles and the Pt-N dipoles are on the same side and give a net dipole.
