Consider the molecule 1-tert-butyl-3-methylcyclohexane. These two groups can be cis or trans. Which arrangement is more stable? Change the bonds between the ring and substituents to wedges and/or dashes to show the proper spatial arrangement of the groups for the more stable arrangement.

2-bromo-2-methylbutane undergoes an e1 elimination reaction in the presence of ethanol. in the next reaction only one of the possible products is represented. although the product shown is not the major product of the reaction, notice that there is more than one way it can be produced. complete the mechanism and draw the missing substances.
