Cyclohexene is most stable in a half-chair [[conformational isomerism|conformation]],<ref>{{cite journal |title= Conformational preferences and interconversion barriers in cyclohexene and derivatives |first1= Frederick R. |last1= Jensen |first2= C.

One basis for the [[cyclohexane conformation]]al preference for a chair is that it allows each bond of the ring to adopt a [[staggered conformation]]. For cyclohexene, however, the alkene is planar, equivalent to an eclipsed conformation at that bond.
