Two chair conformations of cyclohexane are of equal energy. When one of the \(\ce{H}\) is replaced with a bulky group like \(\ce{-CH3}\) group, the bulky group is at an equatorial position in one and at an axial position in the other chair conformation and the two are not the same …
WebAgain, the cis relationship is unaltered by the chair interconversion. The same definition of cis and trans substitution can be applied to substituent groups in other positions of a cyclohexane ring, as illustrated by Study Problem 7.2.
