Give examples of, and suggest reasons for, the following features of transition metal chemistry:
The lowest oxide of a transition metal is basic, whereas the highest oxide is usually acidic.

Give examples of, and suggest reasons for, the following features of transition metal chemistry:

The Halides become more covalent with increasing oxidation state of the metal and are more susceptible to hydrolysis.

Write notes on the following:

The effective Atomic Number rule.

Write notes on the following:

Back bonding in metal carbonyls

Describe the method by which extremely pure samples of the metals may be prepared:

Which of the ${\mathrm{M}}^{2+}$ and ${\mathrm{M}}^{3+}$ ions of the first-row transition elements are stable in aqueous solution, which are oxidizing and which are reducing?

Explain why certain ligands such as ${\mathrm{F}}^{-}$ tend to bring out the maximum oxidation state of an element, whilst others such as $\mathrm{CO}$ and dipyridyl bring out the lowest oxidation states.
