Inorganic Chemistry
Name the factors that affect the thermal stability of alkali metal salts. Explain the stability trend observed in case of nitrates of these metals.
Inorganic Chemistry
1. Show a three-centre two-electron bonding interaction and explain how this confers
stability to the constituent atoms.
2. Use an equation to exemplify the typical reactions for such electron deficient species.
3. Use a suitable example to illustrate the listed reaction types as they occur in metal alkyl
complexes:
(i) Oxidative addition
(ii) Transmetallation
(iii) Reductive elimination
4. Use a diagram to show what you understand by back-bonding.
5. Describe the back bonding you would expect to observe if carbon monoxide coordinates to
iron in Haemoglobin and hence rationalize its toxicity to mammals.
6. What is it about Haemoglobin that allows iron to stay in a low oxidation state (Fe 2+) when
it coordinates to oxygen instead of becoming oxidized to Fe3+ ?

2. Describe two organic reactions of singlet oxygen that would yield different products if normal oxygen were used.
3. Use a diagram to describe the type of bonding occurs between iron and oxygen in Haemoglobin and how this facilitates oxygen transport in mammals.
4. The acid-base properties of two oxides of chromium are shown below: CrO + H2O → Cr(OH)2 basic CrO3 + H2O → H2CrO4 acidic What factors can explain such a vast difference?
5. Rearrange the following oxides in order of increasing basicity ie weakest base to strongest base. Briefly describe your reasoning for the order you choose. Al2O3 P4O10 Na2O SiO2, SO3 MgO Cl2O7
6. Describe one example of a non-stoichiometric oxide and use your example to explain what is meant by metastability in relation to such compounds.
