## Drawing and calculating Keq for cycloalkane …

; and Keq is is the equlibrium constant of a group going from axial to equitorial (a favored shift). Thus a positive A value indicates that a group would much rather be equitorial than axial; as a result, the A values you are given have been DEFINED as values for an AXIAL group going to an EQUITORIAL orientation. Let’s begin with ...
