a) Draw the most stable conformation for cis-1-(1-methylethyl)-2-methylcyclohexane (label this stereoisomer 1) and draw the mirror image of stereoisomer 1 (label this stereoisomer 2).
b) Is stereoisomer 1 superimposeable on stereoisomer 2?
c) Is the ring-flipped conformer of stereoisomer 1 superimposeable on stereoisomer 2?
d) Which is more stable, stereoisomer 1 or its constitutional isomer cis-1-(1-methylethyl)-3methylcyclohexane, isomer 3?
