Conformers of cis-1,2-dichlorocyclohexane

If the ring atoms of cis-1,2-dichlorocyclohexane were planar the molecule would have a plane of symmetry and be achiral. The chair conformations, however, are chiral. The two chair conformers shown here are the result of chair-interconversions, and are enantiomeric. Axial (A) and equatorial (E) chlorine positions are labelled.
