why Ni(nh3)2cl2 does not exihibit isomerism??ques 29
[Ni(NH3)2Cl2] does not show isomerism as it is a tetrahedral molecule and tetrahedral molecules do not show isomerism. This is because, the relative positions of the uni-dendate ligand when attached to central atom are identical. Thus, we see that there is no geometrical isomerism. For stereo-isomerism, the four attached ligand should necessarily be different, but here we have 2 NH3 and 2 Cl.
