4. DRAW the line structure of 2-chloro-5-bromohexane. DRAW the 3 eclipsed Newman projections for this compound above the PES, and the 3 staggered Newman projections for this compound below the PES - Organizing them on a curve of potential energy vs. angle of rotation sighting along the C3-C4 bond. Be sure to draw/label the Newman projections of the conformations that correspond to each energy minimum and maximum. Your curve should clearly indicate the relative stabilities of the different conformations.

Draw a skeletal (bond-line) structure of (R)-2,2,3- trimethylhexane. Use a dash or wedge bond to indicate stereochemistry of substituents on asymmetric centers, where applicable.
Use flat representation of rings, not chair in the drawing. Determine the most and least stable. Consider the most stable chair for each of these isomers, and then draw the most stable and least stable isomer based on a comparison of the best chair for each one.
Paraphrasing .ewriting Tool Pirate Ship Car note BLACKBOARD [Review Toplcs] [References] Cyclohexane derivatives exist primarily in the most stable of the available chair conformations. Give the position, axial or equatorial, of each of the three groups shown when the ring is in the most stable chair conformation. If a group divides its time equally between axial and equatorial positions, indicate this with ax/eq.

4. For the structure shown below, Part A) Draw the Newman projections and 3-D sawhorse structures corresponding to the lowest and highest energy conformations for rotation around the C2-C3 bond. Draw the Newman projections looking FROM THE C2 CARBON TO THE C3 CARBON (i.e. with the C2 carbon in the "front"). Part B) Determine the energy difference between the lowest and highest conformations, and be sure to clearly show each energy contribution that you are including in your calculation.
