Bocknack CH 310M/318M Spring 2009 Graded Homework Problem #07 – Answer Key Deadline : 3:00 p.m., Monday, 3/2/09 LATE WORK WILL NOT BE ACCEPTED OR GRADED!!! This problem is worth a total of 20 raw points. In each part below, complete the chair conformation in the box on the left by filling in the missing substituents. To help you get started, a reference carbon is marked with an asterisk in the tetrahedral representation of the molecule. This reference carbon is also marked with an asterisk in the chair “skeleton” that is provided in the left box. Then, in the empty box on the right , draw the chair conformation that will result upon “chair flip”. Mark the position of reference

Unformatted text preview: carbon in this chair conformation with an asterisk (*)! Finally, indicate which of the two chair conformations is more stable by marking the appropriate box with the symbol X. If both chairs are of equal stability, mark that box. CH 3 CH 3 * = CH 3 H 3 C * tetrahedral representation This chair conformation is more stable. This chair conformation is more stable. Both chair conformations are of equal stability. (a) CH 3 CH 3 CH 2 CH 3 CH 3 H 3 C * = H 3 C CH 2 CH 3 CH 3 This chair conformation is more stable. This chair conformation is more stable. Both chair conformations are of equal stability. (b) CH 3 CH 2 CH 3 CH 3 tetrahedral representation...
