In the chair form of cyclohexane ring bonds to ring atoms (and molecular entities attached to such bonds) are termed axial or equatorial according to whether the bonds make a relatively large or small angle, respectively, with the plane containing or passing closest to a majority of the ring atoms. Thus the axial bonds are approximately parallel to the C3 axis and the equatorial bonds approximately parallel to two of the ring bonds. These terms are also used for the chair form of other saturated six-membered rings., Termin sidemete ja nendega seotud rühmade paiknemise kohta tsükloheksaani tool-konformatsiooni (ja selle derivaatide) puhul, kui sidemed on ligikaudselt selle konformatsiooni põhitasapinnaga risti (põhitasapinna sihilised)
