The paramagnetic species is

The paramagnetic species is

[NiCI_(2){P(C_(2)H_(5))_(2)(C_(6)H_(5))}_(2)] exhibits temperature dependent magnetic behaviour(paramagnetic//diamagnetic) The coordination geometries of Ni^(2+) in the paramagnetic and diamagnetic states are respectively .

Show diagrammatically the behaviour of magnetic field lines in the presence of : (i) Paramagnetic and (ii) Diamagnetic substance, How does one explain this distinguishing feature ?

Find the pair that has the same bond order with diamagnetic and paramagnetic properties respectively.

Can we have magnetic hysterisis in paramagnetic or diamagnetic substances?
