Below are isomers of 1,2-di(2-methylpropyl)cyclohexane in conformational structures. Two are cis and two trans. Indicate which is the more stable conformation for the cis and which for the trans, and indicate which of all the conformations is the most stable. If both conformations of the isomer are equally stable, select both. Select the mote stable conformation of cis-1,2-di(2-methylpropyl)cydohexane. Select the more stable conformation of trans-1,2-di(2-methy1propyl)cyclohexane. Select the most stable conformation overall.
