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 “planar” 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

Unformatted text preview: , draw the chair conformation that will result upon “chair flip”. Mark the position of reference 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 H 3 C * = * "planar representation" This chair conformation is more stable. This chair conformation is more stable. Both chair conformations are of equal stability. (a) CH 3 CH 2 CH 3 CH 3 * = "planar representation" This chair conformation is more stable. This chair conformation is more stable. Both chair conformations are of equal stability. (b)...
