For a $\mathrm{d}^4$ metal ion in an octahedral field, the correct electronic configuration is

Complex $X$ of composition $\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_6 \mathrm{Cl}_n$ has a spin only magnetic moment of 3.83 BM . It reacts with $\mathrm{AgNO}_3$ and shows geometrical isomerism....

$[\mathrm{Pd}(\mathrm{F})(\mathrm{Cl})(\mathrm{Br})(\mathrm{I})]^{2-}$ has n number of geometrical isomers. Then, the spin-only magnetic moment and crystal field stabilisation energy [CFSE] of $\left[\mathrm{Fe}(\mathrm{CN})_6\right]^{\mathrm{n}}{ }^{-6}$, respectively, are [Note :...

The volume (in mL ) of $0.125 \mathrm{M} \mathrm{AgNO}_3$ required to quantitatively precipitate chloride ions in 0.3 g of $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right] \mathrm{Cl}_3$ is $\_\_\_\_$ .
...

Considering that $\Delta_0>\mathrm{P}$, the magnetic moment (in BM) of $\left[\mathrm{Ru}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{2+}$ would be $\_\_\_\_$ .

Consider the complex ions,
trans- $\left[\mathrm{Co}(\mathrm{en})_2 \mathrm{Cl}_2\right]_{\sim}^{+}(\mathrm{A})$ and cis- $\left[\mathrm{Co}(\mathrm{en})_2 \mathrm{Cl}_2\right]_{\sim}^{+}(\mathrm{B})$. The correct statement regarding them is

The complex that can show fac-and mer-isomers is

The crystal field stabilization energy (CFSE) of $\left[\mathrm{Fe}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right] \mathrm{Cl}_2$ and $\mathrm{K}_2\left[\mathrm{NiCl}_4\right]$, respectively, are :

The INCORRECT statement is :
