Which of the following statements best describes the most stable conformation of trans-1,3-dimethylcyclohexane? A) Both methyl groups are axial. 8) Both methyl groups are equatorial. C) One methyl groups is axial, the other equatorial. D) The molecule is severely strained and cannot exist

Explanation / Answer

For the 1st chair from both are not same because I one chair both groups are axial and in another one both are equatorial position so they are not same they are confirmational isomer they can be interchangeable between them via filping.

For the 2nd problem the chair contains both group at equatorial position is trans because 1group is up and another one Is down and another chair contains two groups 1is at equatorial position and another group is in axial position but both group is down so it is cis isomer so both are not same compound.
