Please provide two distinct and unique 3-D representations. Account for all stereochemistry and conformational analysis in your drawing. Clearly identify at least one feature that deviates from conformational expectations. For example, a cyclohexane that, based on your drawing, can not adopt the desired (minimum energy) chair conformation or a stereocenter that's not likely to adopt 109.5 degree bond angles.
