- A trisubstituted cyclohexane with three substituents-red, green, and blue-undergoes a ring-flip to its alternate chair conformation. Identify each substituent as axial or equatorial, and show the positions occupied by the three substituents in the ring-flipped form.Draw the most stable conformation of 1,4-dichlorobutane, using wedges and dashes to represent bonds coming out of the paper and going behind the paper, respectively.Indicate the relationship between each pair. Choose from: configurational stereoisomers,conformers, constitutional isomers, or different formulas (Each term is used at least twice.)
- a model of cyclohexane in a chair conformation, and explain why the names “axial” and“equatorial’ are appropriate.Draw the most stable conformation of pentane, using wedges and dashes to represent bonds coming out of the paper and going behind the paper, respectively.Fill in the blanks: cis-1,3-Dimethylcyclohexane has two different chair conformations: one withboth methyl groups in __________ positions and one with both methyl groups in ____________ positions.
- In the next chapter we'll look at cycloalkanes—saturated cyclic hydrocarbons—and we’ll see that the molecules generally adopt puckered, nonplanar conformations. Cyclohexane, for instance, has a puckered shape like a lounge chair rather than a flat shape. Why?The diaxial conformation of cis-1, 3-dimethylcyclohexane is approximately 23 kJ/mol (5.4 kcal/mol) less stable than the diequatorial conformation. Draw the two possible chair conformations, and suggest a reason for the large energy difference.Which conformation is most unstable?
- Draw the highest and lowest energy conformations. In cases where two or three conformations are degenerate, choose only one as your anwser. Use Pr, Me, H, Et in the structures.Please draw the two most stable conformations (chair conformatoin I beleive) and label the most stable one if possible.Which of these is the most stable conformation?
