- How do you account for the difference in energies between the two staggered conformations of 1,2-dichloroethane? How about for the two eclipsed conformations? Draw all four conformations and, on your drawing, indicate sources of strain – torsional, steric (gauche), steric eclipsed.For the 1,2-dichlorocyclohexane stereoisomers, which conformation of the trans stereoisomer has the lower energy, the diaxial or the diequatorial conformer? Which isomer and conformation of the three you built has the lowest energy? E of all the isomers of 1,2-dichlorocyclohexane. Explain the differences in energy, i.e., identify the sources of strain in the conformations you built. Show the sources of strain in a drawing.I don't understand why the first one and second one are cis and trans respectively. Wouldn't the first one be trans-1,2-dimethylcyclobutane because the torsional strain wouldn't allow the carbons to be in the same conformation. Meaning one of the carbons would be up and then the next would be down and so on. Since both methyl groups are equatorial and the first and second carbons are arranged up and down, wouldn't it be trans. Same logic for the second molecule. Carbon 1, which is attached to the methyl is down, carbon 3 which is attached to the methyl should be down also because of torsional strain, and since both methyl are in axial (or equatorial?), it would be cis. Or is it based off of the way the carbons are positioned in the picture?
- Draw the most stable conformation of the molecule while taking into account the approximate values of the energies of the following skew interactions:Imagine that this worksheet has sucked you the plane of the page, and you are now facing the indicated bond of the drawn molecule. a. Draw the six main Newman projections for the indicated bond: three eclipsed, three staggered. b. Label which conformers are eclipsed ands taggered.c. Identify the most and least stable conformer, and explain your reasoning.Among the figure, (a) what is the most stable conformation of n-pentane? (b) gauche conformation of butane and (c) least stable conformation of butane
- How to solve this question? Would the most stable conformation be staggered (and is it gauche or anti? I can't tell), and the least stable be eclipsed? Not sure how to draw these structures.starting from the wedge and dash structure below, rotate the back carbon to provide the newman projection in the least stable conformationDraw the structure below as a Newman projection looking down the indicated bond in the conformation shown.
- Hello, 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-c341-11e9-8385-02ee952b546eFor the following molecule, draw both chair conformations. Using the rules of cyclohexane substituent stability, circle which is the more stable of the twoCreate a conformational analysis using the molecule in the picture. Follow the instruction in the picture when you transform the molecule into its Newman projection. Which conformer is the most stable? Explain.
