Unformatted text preview: 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 CH 3 * = * tetrahedral representation This chair conformation is more stable. This chair conformation is more stable. Both chair conformations are of equal stability. (a) CH 2 CH 3 CH 3 H 3 C * = This chair conformation is more stable. This chair conformation is more stable. Both chair conformations are of equal stability. (b) tetrahedral representation...
