(c) Draw the alternative chair conformation. Which hydrogens are equatorial? Which are axial? Which are above the plane of the ring? Which are below it?
draw the most stable chair conformation. Where two or more conformations are equally stable, draw both.
Perspective drawings of Chair and Boat Conformers fo Cyclohexane (C6H12). Note it is impossible to place all the carbons in the same plane without straining the bonds. Take two opposite carbons and pull both of them up to make one conformation adn then pull one of them down to make the other conformation. Can you inercovert one conformer int othe other without breaking any bonds? Explain why these represent conformers and not isomers.
For every structure below, draw the most stable chair conformation. Where two or more conformations are equally stable, draw both.
The twist boat conformation is more stable than the boat conformation because a. the hydrogens are completely staggered b. the flagpole hydrogens are farther apart c. the hydrogens exhibit less torsional strain d. Both B and C
Decide which conformation in each pair of compounds is more stable
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-c341-11e9-8385-02ee952b546e
For each attached compound drawn below:a.) Draw representations for the cis and trans isomers using a hexagon for the six-membered ring, and wedges and dashed wedges for substituents.b.) Draw the two possible chair conformations for the cis isomer. Which conformation, if either, is more stable?c.) Draw the two possible chair conformations for the trans isomer. Which conformation, if either, is more stable?d.) Which isomer, cis or trans, is more stable and why?
Consider the most stable chair conformation of all cis-4-tert-butyl-1,2-dimethylcyclohexane (all substituents are cis on the molecule). What is the bond angle between the two methyl groups when looking down the C1-C2 bond? a)45 b)60 c)109.5 d)180
Construct a model of chloroethane, CH3CH2Cl. Remember that these models do not actually show the relative sizes of different atoms. View the model along the carbon-carbon axis and draw the sawhorse and Newman projections of the preferred conformation.
A molecule is achiral if it has a plane of symmetry in any conformation. Each of the attached conformations does not have a plane of symmetry, but rotation around a carbon–carbon bond forms a conformation that does have a plane of symmetry. Draw this conformation for each molecule.
