1. Using the concept of trans activating ligands, predict the following reaction products (A, B, C, D, E, F) Hint: Cl- is greater than py in trans activation.a. [PtCl4]2- + CN- → A + NH3 → B + py → C b. [PtCl4]2- + NH3 → D + CO → E + py → F
a) When [Ni(NH3)4]2+ is treated with HCl, two compounds having the formula [Ni(NH3)2Cl2] (designed X and Y) are formed. X can be converted into Y by diluting in dilute HCl. A solution of X reacts with oxalic acid to form Z complex [Ni(NH3)2C2O4], Y does not react with oxalic acid. Identify X, Y and Z complexes and draw the geometrical structure of them.b) In an unlabelled bottle, it is known to contain potassium diaquadioxalatochromate(III) complex in it. How can...
2) Reaction of the anti-cancer drug cisplatin (Pt(NH3)2Cl2) with water is described by the following equation: Pt(NH3)2Cl2 (aq) + H2O (l) Pt(NH3)2(H2O)Cl+ (aq) + Cl- (q) The rate of this reaction increases by a factor of 15 on raising the temperature from 25oC to 50oC. What is the value of the activation energy in kJ/mol? (3 marks)
Can I please get full working and explanations for each step for
this past exam question. Both parts (a) and (b) and (c). Thanks

Question B1 The isomerisation shown below has an equilibrium constant of K = 0.74 k1 trans-Co(en)2(H2O)OH) k1 cis-Co(en)2(H2O)(OH)2 The kinetics of the reaction was followed and it was found that a plot of the natural log of the concentration of the cis isomer ('cis') minus its equilibrium concentration (In([cis]- [cis]eq) versus time gave a...
Are there any other spectroscopic techniques, other than UV-Visible spectroscopy, which might be able to distinguish between the cis- and trans-[Co(en)2Cl2]Cl diastereomers? For example, IR or 1H nmr? For those techniques, explain what you might expect to observe that would or would not assist you in assigned the stereo-chemistry of the green and violet isomers.
Write the chemical names for the following compounds (if the metal is in a complex ion, be sure to include its oxidation number!) a. Rb[AgF4] b. fac-[Re(bpy)(CO)3Cl] c. [Co(NH3)5(H2O)]SO4 d. [Ag(NH3)2][PF6] e. mer-[Fe(H2O)3I3] f. trans-[CoCl2(en)2]Cl g. [Ni(bpy)3](NO3)2 h. Mo(CO)6 2. Sketch all optical and/or geometric isomers of the following: a. [Pt(NH3)3Cl3] + b. [PtCl2(en)2] 2+ c. Pt(NH3)2Cl2
SYNTHESIS OF TRANSITION METAL COORDINATION COM 3. Ethylenediamine ("en" in short-hand notation) has two amine groups, one at each end of a two-carbon chain, NH,CH,CH,NH. Each nitrogen in NH,CH,CH_NH, has a lone pair that coordinates to the metal. Thus, one NH CH CH NH, ligand, takes up two coordina- tion sites. a) Draw and label the structures of the cis and trans isomers of Co(en),C1,CI. b) What is the coordination number for (Coſen),C1,CI? c) Determine the oxidation state of the...
