Draw the two molecules in theirmost stable chair conformers (IUPAC name: 2-isopropyl-5-methylcyclohexanol).arrow_forwardHello, I was reading an answer from the book Organic Chemistry by Brown et al. The question is 2.51 "Draw alternative chair conformations for each substituted cyclohexane and state which chair is more stable." There are then 4 cyclohexanes (labeled a-d). For the "a" cyclohexane, the substituents are arranged as a combination of axial and equatorial in both chair conformations. However, for the "b," "c," and "d," cyclohexanes one chair has only equatorial substituents, and the other chair has only axial substituents. Why is the "a" chair conformation different? https://www.bartleby.com/solution-answer/chapter-2-problem-251p-organic-chemistry-8th-edition/9781305580350/draw-alternative-chair-conformations-for-each-substituted-cyclohexane-and-state-which-chair-is-more/4532cd91-c341-11e9-8385-02ee952b546earrow_forwardIllustrate a Newmann projection for the most stable conformation of the following molecule looking down the C3-C4 bondarrow_forward
