Extra Practice: Interconverting Representations of Cyclohexane SOLUTIONS To convert a 2D wedge-dash structure of a substituted cyclohexane molecule into a chair: 2D wedge-dash structure showing one wedge substituent location One conformation (6 of 12 possibilities shown) These 6 representations differ by viewing angle/chair template, but are of the same structure in the same conformation. Exercise: Find the other 6 representations. Answer: “Pancake flip” each of the above structures so that Group A points downward. The other conformation (after a chair flip) (6 of 12 possibilities shown) These 6 representations differ by viewing angle/chair template, but are of the same structure in the same conformation. Exercise: Find the other 6 representations. Answer: “Pancake flip” each of the above structures so that Group A points downward. Exercise 2D wedge-dash structure Exercise: Add in substituent F on each chair template. When adding substituent F, pay attention to its position on the cyclohexane ring, its relationship to substituent A, and the bond angles. One conformation (6 of 12 possibilities shown) The other conformation (after a chair flip) (6 of 12 possibilities shown)
