WebThe cis/trans geometry of the final product is directly decided by the difference between conrotation and disrotation. Determining whether a particular reaction is conrotatory or disrotatory can be accomplished by examining the molecular orbitals of each molecule and through a set of rules. WebCis and Trans isomerism only happens around an alkene because they're locked into the positions thanks to the pi structure. You don't get any rotation around a pi bond whereas you do around a sigma bond so theres no cis and trans for alkanes
