The reaction of indium, In, with sulfur leads to three binary compounds, which we will assume to be purely ionic. The three compounds have the following properties: Compound Mass % In Melting Point (ºC) A 87.7 653 B 78.2 692 C 70.5 1050 a. Determine the empirical formulas of compounds A, B, and C. b. Give the charge of In in each of the three compounds. c. Write the electron configurations (shorthand) for the In in each compound. Do any...
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...
