However in small and medium size rings this is not the case; here the cis -cycloalkene is more stable than the corresponding trans isomer.
Web• b) Cis-Trans Isomerism in Alkenes • Carbon atoms in a double bond are sp2-hybridized – Three equivalent orbitals at 120°separation in the plane • Interaction of p orbitals, one bonding and one antibonding molecular orbital • Rotation prevented by bond • Barrier to double-bond rotation must be as great as the strength of p bond ... 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 …
