4. Alkanes and Cycloalkanes / Barrier To Rotation / Problem 7

Assume that the temperature is 298 K. Consider the following bond rotation and use the given table to answer the questions below:


Two conformations of a cycloalkane with NH2 and CH3 groups, showing bond rotation.
Table showing strain values for 1,2-Gauche conformations of CH3-CH3 and NH2-CH3.


(a) Which conformation is more stable? 
(b) Determine the ΔG° for the process. 
(c) Determine the equilibrium constant (Keq).
(d) Provide the transition state for the process.
