MCH-016 Inorganic Chemistry 2 Assignment Questions
Course Code: MCH-016
Course Title: Inorganic Chemistry 2
Maximum Marks: 100
Note: Attempt all questions. The marks for each question are indicated against it.
Question 1
a) What are the kinetic consequences of reaction pathways like dissociation, interchange and association for substitution reactions. (5)
b) Arrange the following in order of increasing rate of water exchange: [Ti(H₂O)₆]³⁺, [Co(H₂O)₆]²⁺, [Cr(H₂O)₆]³⁺, [Zn(H₂O)₆]²⁺. Justify your answer. (5)
Question 2
a) Explain the conjugate base (CB) mechanism, that is the base catalyzed hydrolysis. Give suitable diagrams for this. Give one example where hydrolysis leads to complete retention of configuration in which there is deprotonation of the amino group. (5)
b) Why are polydentate complexes more thermodynamically stable than their monodentate counterparts? Explain the Ray-Dutt (rhomboid) twist mechanism for intramolecular racemization. (5)
Question 3
a) Explain the mechanism of dissociation and stereochemical changes for cis-[M(LL)₂BX] with the help of suitable diagrams. (5)
b) With the help of a suitable example explain the role of the entering group in the substitution of square planar complexes. (5)
Question 4
a) Give the situations when dissociate mechanism would be predicted for substitution in octahedral complexes. (5)
b) If we compare the four-coordinate complexes Cd–N₂S and Cd–N₂O, the former undergoes stereochemical inversion more rapidly than the latter. What is the most probable reason for this behaviour? (5)
Question 5
a) Comment on ligand reducibility, electron transfer and the rate constants for the reaction:
[Co(NH₃)₅(L)]²⁺ + [Fe(H₂O)₆]²⁺ → Co²⁺ + H₂O + 5NH₃ + [Fe(H₂O)₅(L)]²⁺
| L | k₂ (M⁻¹s⁻¹) | Comment |
|---|---|---|
| HCOO⁻ (formate) | 0.22 | Formate is difficult to reduce |
| CH₃COO⁻ (acetate) | 0.45 | Acetic acid is difficult to reduce |
| C₂O₄²⁻ (oxalate) | 8.5 | Oxalate is more reducible |
| HOOCCH₂COO⁻ (malonate) | 95 | Malonate is easy to reduce |
| NCS⁻ (thiocyanate) | 2.5 × 10³ | Thiocyanate is very easy to reduce |
(5)
b) What are mixed valence complexes? How are the oxidation states of the metal centres in such complexes categorized in the case of electron transfer reaction? (5)
Question 6
a) What structural features make siderophores highly selective for Fe(III)? Why are they also known as siderochromes? Why is Fe(III) more commonly transported by siderophores than Fe(II)? (5)
b) Explain why iron in hemerythrin does not bind oxygen through a heme group. Explain the oxidation state changes that occur during oxygen binding in hemerythrin. (5)
Question 7
a) What are the common types of iron–sulfur clusters found in ferredoxins? Where are the iron sulphur proteins located? How do ferredoxins differ from rubredoxin? (5)
b) Discuss the coordination environment of Mg(II) in chlorophyll and compare it with Fe(II) in hemoglobin. Explain how transition metal ions participate in photosynthetic electron transfer. (5)
Question 8
a) Describe the mechanism of oxygen evolution from water in Photosystem II. Discuss the structure of the active site of carboxypeptidase A. (5)
b) Discuss the mechanism of proton transfer in carbonic anhydrase. (5)
Question 9
a) Explain the way metal complexes may be used to probe the local conformational changes that may happen in the nucleic acid polymers. (5)
b) What are the two main types of transition-metal complex reactions with polynucleotides? Give suitable examples and chemical equations for them. (5)
Question 10
a) What are the differences between Hypernatremia and Hypokalemia? Give the diseases that may arise due to deficiency of zinc. (5)
b) How have metals been used for MRI? Give a short account. (5)
