Answer the following:
(i)[1.0]
$[\text{Co}(\text{NH}_3)_6]^{3+}$ is an inner orbital complex whereas $[\text{CoF}_6]^{3-}$ is an outer orbital complex. Why? (Given: Atomic number of $\text{Co} = 27$).
(ii)[1.0]
A coordination compound with molecular formula $\text{CrCl}_3\cdot6\text{H}_2\text{O}$ precipitates two moles of $\text{AgCl}$ with $\text{AgNO}_3$ solution. Write the structural formula of the compound.
(iii)[1.0]
Explain why an aqueous solution of $\text{K}_4[\text{Fe}(\text{CN})_6]$ is not toxic whereas an aqueous solution of $\text{KCN}$ is highly toxic.
