What the assignment asks
| Question | Marks | Topic |
|---|---|---|
| Q1 | 5 + 5 | Discuss metal melting-point trends and use VSEPR theory to predict the shape of sulfur tetrafluoride. |
| Q2 | 5 + 5 | Assess inorganic aromaticity in specified sulfur-nitrogen species and describe the synthesis of mixed-substituent phosphazene polymers. |
| Q3 | 5 + 5 | Classify organotransition metal alkyls and aryls, and explain fluxional compounds and their identification by NMR. |
| Q4 | 5 + 5 | Calculate the effective atomic number of a manganese carbonyl nitrosyl complex and explain synergic bonding in metal carbonyls. |
| Q5 | 5 + 5 | Discuss dinitrogen complexes and their preparation, and describe the preparation of cobaltocene dioxygen adducts. |
| Q6 | 5 + 5 | Examine the preparation and bonding modes of a metal-dinitrogen complex and explain the Tolman cone angle of phosphines. |
| Q7 | 5 + 5 | Describe molybdenocene preparation and its reaction with ethylene, and discuss heterocarboranes and a multidecker metal sandwich complex. |
| Q8 | 5 + 5 | Apply the Jahn–Teller effect to specified complexes and compare octahedral and tetrahedral site preferences for chromium and manganese ions. |
| Q9 | 5 + 5 | Discuss lanthanoid magnetic moments and superexchange, and explain intermolecular antiferromagnetism through direct metal interaction. |
