Write the formula of the coordination compound tris(bipyridine)iron(II) bromide. Enclose complexes in square brackets, even if there are no counter ions. Do not enclose a ligand in parentheses if it appears only once. Enter water as H2O. If any abbreviations are given in blue below, you must use them in your answer. Enclose abbreviations in parentheses if there are more than one. C30H24CL2FEN6 X Name the coordination compound Li4[Zr(C204)4]. Give the chemical formula of the following coordination compound. Enclose complexes...

The two isomers are: [Co(NH3)5ONO]Cl2 and [Co(NH3)5NO2]Cl2. 1. Draw Lewis structures for both isomers, making sure to highlight what the difference between them is, and what the charge on cobalt is. (Note: In your drawing, you don't have to draw the entire structure and all the bonds within each ammonia ligand (the N-H bonds), but you should for the NO2. It should be clear what atom from each ligand binds to the cobalt ion). 2. Which isomer do you expect...

Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...

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...

11. (a) Consider two metal plates with equal but opposite charges +Qand - as in Fig. 11(a), separated by a distance d. Sketch the charge distribution within the positively-charged plate. Note that the plate should have finite thickness in your diagram. (2 marks) ii. What is the magnitude of the electric field inside a conductor? Explain briefly your answer. (2 marks) iii.

Analyze each pair of compounds structures represent. Your cho cach pair of compounds below. Identify which class of isomers each pair of s represent. Your choices are: (i) constitutional, (ii) conformational, (iii) omers, (iv) diastereomer or (v) identical (non-isomers). Only one label for each pair should be used. For each case show work (drawings, (R)/(S), rotation of bonds, chair- "ps, etc) which led you to each answer for the pairs below. Any differences of answers between you and your peers...
