The CN of `Ni^(+2)=4`
`NiCl_(2)+KCN_("excess")toA` (cyano complex)
`NiCl_(2)+conc.KCl_("(excess)")toB` (Chloro complex)
Predict the magnetic nature of A and B

A

Both the diamagnetic

B

Both are paramagnetic

C

A is diamagnetic and B is para magnetic with 1 unpaired `e^(-)`

D

A is diamagnetic and B in para magnetic with 2 unpaired `e^(-)`

Text Solution

Verified by Experts

`K_(2)[underset((A))Ni(CN)_(4)]to` Diamagnetic is SFL, all electron gent paired.
`K_(2)[underset((B))Ni(Cl)_(4)]to` Paramagnetic, 2 unpaired electrons is WFL.
