Please assist with 4a and 4b--draw two chair conformations for molecules listed

a. Draw the two chair conformations for cis-1,4-dimethylcyclohexane. Use the given template. In the conformation on the left, all atoms bonded to carbon 1 have been drawn. You need to complete the rest of the structure. In the conformation on the right, fill in the two boxes at carbon 1 and complete the rest of the structure. b. Identify the molecule for which the two chair conformations are expected to have the same energy. Completely fill in the circle in front of your choice. cis-1,3-dichlorocyclohexane cis-1,4-dichlorocyclohexane trans-1,2-dichlorocyclohexane
