Some square planar complexes of Ni(II) are diamagnetic while some others are paramagnetic. Justify. |
Answer» Solution : In some complexes, the two UNPAIRED 3d ELECTRONS pair up and the HYBRIDISATION is `dsp^(2)`. Thus, no unpaired electron is LEFT. In some other complexes, one unpaired 3d electron is excited to 4p. Hybridisation is again `dsp^(2)` but there are two unpaired electrons present. |
