This leads to a staggered conformation in chair form reducing torsional strain. However if there are more groups on the cyclohexane we need to take into consideration the 13-diaxial interaction of all. Chair conformation of cyclohexane is more stable than boat form because in chair conformaion the C-H bonds are equally axial and equatorial ie out of twelve C-H bonds six are axial and six are equatorial and each carbon has one axial and one equatorial C-H bond. For the second chair the methyl groups position on an axial bond will cause steric strain which will reduce the stability of the chair. It has equatorial and axial bonds.
By drawing cyclohexane in a chair conformation we can see how the Hs are positioned.
Ideally more stable chairs wil have the larger groups on equatorial bonds. It has equatorial and axial bonds. Chair conformation is the most stable structure of cyclohexane. These are hydrogens in the axial form.
