Substituted cyclohexene

WebIn examining possible structures for substituted cyclohexanes, it is useful to follow two principles: (i) Chair conformations are generally more stable than other possibilities. (ii) Substituents on chair conformers prefer to occupy equatorial positions due to the increased steric hindrance of axial locations.
