Answer any five of the following :

How is the crystal field splitting energy for octahedral complex $\displaystyle \left(\Delta_{0}\right)$ related to that of tetrahedral complex $\displaystyle \left(\Delta_{\mathrm{t}}\right)$ ?

Write the IUPAC name of the following complex : $\displaystyle \left[\mathrm{PtCl}_{2}(\mathrm{en})_{2}\right]\left(\mathrm{NO}_{3}\right)_{2}$

Write the geometry and magnetic behaviour of the complex $\displaystyle \left[\mathrm{Ni}(\mathrm{CO})_{4}\right]$ on the basis of Valency Bond Theory (VBT).

What type of isomerism is shown by the complex $\displaystyle \left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{6}\right]\left[\mathrm{Cr}(\mathrm{CN})_{6}\right]$ ?

For the coordination compound on the basis of crystal field theory, write the electronic configuration for $\displaystyle \mathrm{d}^{4}$ ion if $\displaystyle \Delta_{0}<\mathrm{P}$. Is the coordination compound a high spin or low spin complex ?

Out of $\displaystyle \left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{6}\right]^{3+}$ and $\displaystyle \left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{4} \mathrm{Cl}_{2}\right]^{+}$, which complex is heteroleptic and why ?

Draw the structures of optical isomers of $\displaystyle \left[\mathrm{PtCl}_{2}(\mathrm{en})_{2}\right]^{2+}$.
