Which of the following complexes, how many of them are paramagnetic & diamagnetic in nature respectively :-

\left[{Ni}({CO})_4\right],\left[{Cr}\left({NH}_3\right)_3\left({NO}_2\right)_3\right]

\left[{Ni}\left({NH}_3\right)_3\left({H}_2 {O}\right)_3\right]^{+2},\left[{Co}({OX})_3\right]^{-3}

\left[{Fe}\left({NH}_3\right)_6\right]^{+3},\left[{NiCl}_4\right]^{-2}

Options are :

View answer and explanation

Correct option: C

4, 2

Option C (4, 2) is correct because 4 complexes are paramagnetic and 2 are diamagnetic after determining the electronic configuration and presence of unpaired electrons.
