- Consider the molecule 1-bromo-2-methylbutane. C3 and C4 should be drawn as Et as in theexample. This group is called an ethyl group and can be considered a sphere about twice the sizeof a methyl group. Draw the following Newman projections sighting down the C1C2 bond... a. The lowest potential energy conformation. b. The highest potential energy staggered conformation.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.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.
- 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 1,4-dichlorobutane, using wedges and dashes to represent bonds coming out of the paper and going behind the paper, respectively.
- 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?Identify the highest and lowest energy conformation.
