Question

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 can be discussed and corrected as needed. Note: Various projections may be used when drawing chemical structures including bond- line structures (using proper dash/wedge bonds), Newman projections, chair structures (for cyclohexane derivatives), Haworth projections, and Fischer projections. These projections just represent different vantage points of visualizing a chemical structure and can be interconverted from one projection to another. Each different projection has been labeled for you below. These are all utilized throughout the text book.

Answer 1

The answer to the above question with all the sub parts have been explained as below.

W vs A = Constitutional isomer Both chair structure, Constitutional rsomers are the structural isomers having same molecular formula but they have different bonding pattern - different structure. Newman str. h = 5 - As the groups have been changed so the coiginal is 'R' So this is pair of enantiomers (fist is R s seand is s) Line stoveture chair structure Both suctures are identical (Non icomers)
