Conjugation and hyperconjugation in conformational analysis of cyclohexene derivatives containing an exocyclic double bond

The equilibrium geometry, as well as the conjugation and hyperconjugation occurring in the conformational analysis of the cyclohexene derivatives containing an exocyclic double bond are explained. The equilibrium conformation of the ring present in the system is shown to be highly dependent on the conjugation taking place between the endocyclic and exocyclic double bonds.
