Unformatted text preview: Question 1. 5. From the conformations for the compounds in Question 1, select conformation that would be examples of torsional strain, steric strain, and combined torsional and steric strain. Note: Not all compounds will exhibit all of the forms of strain. 6. The following substance was prepared and studied ( J. Org. Chem. , 1996 , 61 , 4634). A) Provide a clear drawing of the other chair conformation that is in equilibrium with the one shown here. O C CH 3 O N B) Is the equilibrium constant for this chair-to-chair interconversion >1, 0, or <1? Provide the speciFc structural rationalization for this prediction as applied to this substance. C) A common incorrect answer to part (A) is shown below. Why is this incorrect? O CH 3 C O N...
