Questions
Questiоn 12 (26 tоtаl pоints). For 3-ethyl-2-methylpentаne (line-аngle structure provided below): part A (13 points) Draw Newman projections AND 3-D sawhorse structures corresponding to the lowest AND highest energy conformations for rotation around the C2-C3 bond. Draw the Newmans looking FROM THE C2 CARBON TO THE C3 CARBON (i.e. with the C2 carbon in "front"). Draw each 3D-sawhorse structure from the perspective of viewing the corresponding Newman projection FROM THE RIGHT. Clearly label which Newman/Sawhorse corresponds to the lowest energy conformation and which corresponds to the highest energy conformation. part B (13 points) Determine the ENERGY DIFFERENCE between these conformations (use the data in either the table below or in the table on the cover page of this test). Be sure to clearly identify each energy contribution, listing both the relevant individual interactions and the corresponding interaction energies (for both conformations), that you take into account when answering this question.
