Concept explainers
(a)
Interpretation:
The coordination number of the metal ion and the number of individual ions per formula unit have has to be given.
Concept introduction:
Coordination number:
The coordination number is the number of ligand atoms bonded directly to the central metal ion in a complex ion.
Oxidation number: (Oxidation state) A number equal to the magnitude of the charge an atom would have if its shared electrons were transferred to the atom that attracts them more strongly.
- 1. The cation is named before the anion.
- 2. Within a complex ion, the Ligands are arranged in an alphabetical order followed by the metal ion name. The anionic Ligand should ends with a letter –o, the neutral Ligand are called by the molecules (some common name for some exception).
- 3. When more Ligands are present, Greek prefixes like di, tri, tetra, penta, and hexa to specify their number.
- 4. The oxidation number of the metal is represented in roman numerals immediately following the metal ion name.
- 5. If the complex ion is an anion, the metal name should end with –ate.

- CHEM 310 Quiz 8 Organic Chemistry II Due: Tuesday, April 25th, at 11:59 pm. This quiz is open textbook / open notes - but you must work alone. You cannot use the internet or the solutions manual for the book. Scan in your work and record an explanation of your mechanism. You may record this any way that you like. One way would be to start an individual Zoom meeting, start recording, "share your screen" and then talk through the problem. This will be converted to an .mp4 file that you can upload into Canvas using the "record/upload media" feature. Pyridine, benzoic acid and benzene are dissolved in ethyl acetate. Design and provide a plan / flow chart for separating and isolating each of these components. Pyridine and benzene are liquids at room temperature. Benzoic acid is a solid. You have ethyl acetate, 2M NaOH, 2M HCI and anhydrous MgSO4 available, as well as all the glassware and equipment that you used in the organic lab this year. Provide accurate acid/base reactions for any…arrow_forwardCan anyone help me solve this step by step.
