For the complex ion ${\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]}^{3-}$ , state the type of hybridisation.

For the complex ion ${\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]}^{3-}$ , state the magnetic behaviour.

For the complex ion ${\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]}^{3-}$ , state the oxidation number of the central metal atom.

Write the IUPAC name of ${\left[\mathrm{Co}{\left(\mathrm{en}\right)}_2{\mathrm{Cl}}_2\right]}^{+}$ion and draw the structures of its geometrical isomers.

When a coordination compound ${\mathrm{CoCl}}_3.6{\mathrm{NH}}_3$ is mixed with ${\mathrm{AgNO}}_3$, three moles of $\mathrm{AgCl}$ are precipitated per mole of the compound. Write the structural formula and IUPAC name of the coordination compound.

Name of the type of isomerism exhibited by the following pairs of compounds: $\left[\mathrm{Cr}{\left({\mathrm{H}}_2\mathrm{O}\right)}_4{\mathrm{Cl}}_2\right] \mathrm{Cl}.2{\mathrm{H}}_2\mathrm{O}$ and $\left[\mathrm{Cr}{\left({\mathrm{H}}_2\mathrm{O}\right)}_5\mathrm{Cl}\right]\mathrm{C}{\mathrm{l}}_2.{\mathrm{H}}_2\mathrm{O}$.

Name of the type of isomerism exhibited by the following pairs of compounds: $\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_6\right] \left[\mathrm{Cr}{\left(\mathrm{CN}\right)}_6\right]$ and $\left[\mathrm{Cr}{\left({\mathrm{NH}}_3\right)}_6\right] \left[\mathrm{Co}{\left(\mathrm{CN}\right)}_6\right]$.

Using the valence bond approach, predict the shape, hybridisation and magnetic behaviour of $\left[\mathrm{Ni}{\left(\mathrm{CO}\right)}_4\right]$. (at. no. of $\mathrm{Ni}=28$).
