- 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?Consider the Newman projection below. a. Draw a full Lewis structure of this molecule with R1=Me,R2=Et , and R3=iPr . b. Given the sizes of these R groups (R3R2R1) , does the Newman projection above show thelowest potential energy conformation of this bond? If not, draw a Newman projectionshowing the lowest P.E. conformation (sighting down this same bond). c. To draw a Newman projection in the lowest P.E. conformation, the following rule of thumbusually applies: Place the largest group on the front carbon anti to the largest group on theback carbon. Is your answer to the previous question consistent with this rule of thumb?3)- Determine the total number of conformers and draw the Chair Structures of the conformers for the Tri-substituted cyclohexane structure given below (i.e., "A"). Draw the relative energy diagram for the possible conformers for the cyclohexane structure below. Note, draw only the required structures for the conformers of A. Also, include hydrogen atoms wherever there are substituents on all of your chair conformers. Answer (Total #of Conformers): Chair Structures: Relative Energy Diagram 8 bas roll 3
