- Build a model of methylcyclohexane, and use the model to complete the following Newmanprojections of methylcyclohexane in the chair conformation: a. When the methyl group is in an axial or equatorial (circle one) position, the molecule is inits lowest potential energy conformation. b. Label one Newman projection above anti and the other gauche to describe the relationshipbetween the methyl group and C3 of the ring. c. In general, which is a lower PE conformation, anti or gauche? d. Explain how your answer to b and c provide an explanation for why it is more favorable fora large group to be in an equatorial than an axial position.Draw a structural formula for 2-cyclopenten-1-ol. • Show stereochemistry only if given in the name. • If a group is achiral, do not use wedged or hashed bonds on it. • In cases where there is more than one answer, just draw one.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.
- For each of the following disubstituted cyclohexanes, indicate whether the substituents in the two chair conformers will be both equatorial in one chair conformer and both axial in the other (A) or one equatorial and one axial in each of the chair conformers (B): Drag the appropriate items to their respective bins.I know the main chain is cyclononane but the numbering for the substituents is where I have trouble(a) Use the polygon rule to draw an energy diagram for the MOs of a planar cyclooctatetraenyl system. (b) Fill in the eight pi electrons for cyclooctatetraene. Is this electronic configuration aromatic or antiaromatic? Could the cyclooctatetraene system be aromatic if it gained or lost electrons? (c) Draw pictorial representations for the three bonding MOs and the two nonbonding MOs of cyclooctatetraene. The antibonding MOs are difficult to draw, except for the all-antibonding MO.
- Which of the following alkenes have the Z designation? Choose all that apply.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?Explain why alkene A is more stable than alkene B, even though Bcontains more carbon atoms bonded to the double bond. Would youexpect C to be more or less stable than A and B?
- Which of the following rings is the most strained? cyclopropene; cyclopropane; cyclobutane; cyclopentane; cyclohexane after finding the most strained compound explain why and compare it to the other answer choices, explaining why they do not work as an answer.Explain why alkene A is more stable than alkene B, even though B contains more carbon atoms bonded to the double bond. Would you expect C to be more or less stable than A and B?When you obtained a geometry optimized structure of methylcyclopentane, did you determine the energy of the most stable conformation? Why or why not?
