Due by 5:00 pm, Wednesday, November 15, 2023. Late papers will not be accepted. Place your answers directly on this worksheet and staple extra pages to it if needed. Feel free to work with other students but each person needs to hand in their own individual copy. Note that R = 1.987 x 10-³ kcal/mol K = 8.314 x 103 kJ/mol·K 10. (10 points) Consider 1,2-ethanediol, also known as ethylene glycol, the major component of antifreeze, HO-CH₂CH₂-OH. a. Draw Newman projection formulas about the C-C bond for the eclipsed, gauche, and staggered (anti) conformations. b. Computational studies have suggested that, unlike most compounds, the gauche conformation is the low energy conformation; being 2.3 kcal/mol lower in energy than the anti. Explain this observation in 2-3 sentences below. Hint: think inter/intramolecular interactions. compound below that has the bi 3. The compound R te
