Part A) Draw the Newman projections and 3-D sawhorse
structures for BOTH the HIGHEST and LOWEST energy
conformations (clearly indicate which is which). Your Newman
projections should look FROM carbon 2 to carbon 3 (i.e. with
the C2 carbon in the "front").](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6965497d-0067-4388-9985-52637dc8de05%2F7d117a6e-c5fe-4c3f-8c1a-29263aa53de3%2Fp4temg9_processed.png&w=3840&q=75)
