Exercise 1

Select the incorrect statement.

The pair of compounds having metals in their highest oxidation state is:

One mole of the complex compound $\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_5{\mathrm{Cl}}_3$ gives $3$ moles of ions on dissolution in water. One mole of the same complex reacts with two moles of ${\mathrm{AgNO}}_3$ solution to yield two moles of $\mathrm{AgCl}$$\left(\mathrm{s}\right)$. The structure of the complex is:

A complex compound whose central metal is in its $+1$ oxidation state with coordination number two can show which isomerism?

$\left[\mathrm{Cr}{\left({\mathrm{NH}}_3\right)}_5\mathrm{Br}\right]\mathrm{Cl}$ and $\left[\mathrm{Cr}{\left({\mathrm{NH}}_3\right)}_5\mathrm{Cl}\right]\mathrm{Br}$ can be distinguished by/and isomerism shown is 

The complex ${\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_5\left(\mathrm{ONO}\right)\right]}^{2+}$ can exhibit

Select the correct statement about the complex $\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_5{\mathrm{SO}}_4\right]\mathrm{Br}$.

The type of isomerism which is shown by ${\left[{\mathrm{PtCl}}_2{\mathrm{Br}}_2\right]}^{2-}$ is also observed in
