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.

OH H VS (b) HECH Both are chair structures Newman projection bond-line structure (dash/wedge shown) Br (d) OH in vs он chair structure ond-line structure ash/wedge shown) bond-line structure (dash/wedge shown) bond-line structure (dash/wedge shown) Dicast Analyze the structures for Compound A and Compound B shown below. Answer and Biscuss each question (a) and (b), respectively. a. What type of isomers do these represent? b. Which compound is more stable? (Hint: You will need to draw the chair structures for each compound (4 total chairs, two for each compound) and compare/contrast/analyze the various 1,3-diaxial interactions in order to justify this answer. Show your work clearly. Compound A Compound B CH₃ on
