WebA stereogenic element is a center, axis or plane that is a focus of stereoisomerism, such that an interchange of two groups attached to this feature leads to a stereoisomer. Stereogenic elements may be chiral or achiral. An asymmetric carbon is often a chiral stereogenic center, since interchanging any two substituent groups converts one ... WebDisubstituted cyclohexanes, like monosubstituted cyclohexanes, can be subjected to confor-mational analysis.
