Cyklohexans konformation
WebBy symmetry, the cyclohexane on the right requires each carbon atom to have a C − C − C angle of 120 degrees. From VSEPR theory, this is not optimal for tetrahedral carbon. A regular tetrahedron has angles between vertices of approximately 109.5 degrees and the equilibrium bond angles of a secondary carbon won't be too discrepant from this.

WebFigure 3: Chair conformation of cyclohexane. The H-atoms form two types of bonds in a cyclohexane molecule, six axial bonds and six equatorial bonds. Therefore, there are two types of H-atoms in cyclohexane – axial (Ha) and equatorial (Heq). (A tip to remember the bonds is to first draw the axial bonds, one up and the next down, and so on.
