methylcyclohexane conformations

 

methylcyclohexane conformations:

1) Methylcyclohexane is cyclohexane in which one hydrogen atom is replaced with a methyl group substituent. 

2) Methylcyclohexane can adopt two basic chair conformations: one in which the methyl group is axial, and one in which it is equatorial. 

3) The most stable conformation of methylcyclohexane is the chair conformation in which the methyl group is equatorial.

4) The alternative chair conformation, in which the methyl group is axial, is 7.3 kJ/mol higher in energy. 

5) This difference corresponds to a equatorial:axial conformer ratio of 19:1 at 

25 °C.
