WebFor example, the difference in energy between the two chair conformations of tert-butyl cyclohexane (24 kJ/mol) is much larger than for methylcyclohexane (7 kJ/mol), because a tert-butyl group is larger than a methyl group and results in more energetically unfavorable 1,3-diaxial interactions. WebThis allows us to see all the eclipsed hydrogens and all of the torsional strain, so the boat conformation is much higher in energy compared to the chair conformation, the chair conformation is the lowest in energy.
