| List I | List II | ||
|---|---|---|---|
| P. | $$[Cr{(N{H_3})_3}C{l_2}]Cl$$ |
1. | Paramagnetic and exhibits ionisation isomerism. |

4. | Diamagnetic and exhibits ionisation isomerism. |
Consider the following complex ions : P, Q and R.
$$P = {[Fe{F_6}]^{3 - }}$$, $$Q = {[V{({H_2}O)_6}]^{2 + }}$$ and $$R = {[Fe{({H_2}O)_6}]^{2 + }}$$
The correct order of the complex ions, according to their spin-only magnetic moment values (in B.M.) is
The pair(s) of coordination complexes/ions exhibiting the same kind of isomerism is(are)
$$NiC{l_2}{\{ P{({C_2}{H_5})_2}({C_6}{H_5})\} _2}$$ exhibits temperature-dependent magnetic behaviour (paramagnetic/diamagnetic). The coordination geometries of Ni2+ in the paramagnetic and diamagnetic states are, respectively,
