Question

or trans where approprium or stereoisomers. 5. Using only chair conformations, make and draw molecular models for all of the 1.4. dibromocyclohexanes. Clearly indicate which are related as conformational isomers and which are related as configurational isomers. Designate the configurational isomers as cis or trans. Explain which isomers equilibrate rapidly with each other interconvert). 6. Draw the two chair conformations of trans-1,4-dichlorocyclohexane. Construct a qualitative plot (reaction energy diagram) that describes the energy of the system as a function of the progress of the interconversion of one conformational isomer into the other. Be sure to clearly indicate the coordinates on the diagram that correspond to the different conformations. Specify the energy differences that control the rate of the equilibrium reactions (there is both a forward and backward reaction rate). Using a model of 1,4- dichlorocyclohexane, explain in words how your diagram corresponds to changes in the molecular structure.
