NiCl_(2)overset(KCN)underset(HCN) to "Complex " A NiCl_(2)overset(KCN)underset(excess) to "Complex " B A and B complexes have the co-ordination number 4. What are the magnetic nature of A and B ?

Answer»

Both diamagnetic.
A is diamagnetic and B is paramagnetic with ONE unpaired electrons.
A is diamagnetic and B is paramagnetic with two unpaired electrons.
Both are paramagnetic.

Solution :`A to underset(dsp^(2)("diamag".))(K_(2)[NI(CN)_(4)]),""B to underset(sp^(3)(2 u.p.e^(-)))(K_(2)[NiCl_(4)])`
