1. Predict whether compound A will provide compound C or compound D if treated with NaOCH3 in methanol in an E2 reaction and briefly explain the reason for your choice. 2. Predict whether compound B will provide compound C or compound D if treated with NaOCH3 in methanol in an E2 reaction and briefly explain the reason for your choice. 3. Predict whether compound A or compound B will undergo E2 reaction at the faster rate and briefly explain your answer. To answer all parts of this question you will need to consider the two ring-flip conformers for A and for B and which of the two ring-flip conformers will be more abundant for A and for B. I have drawn them minus the bromine, so you would need to redraw them and place I-1 and Br at the asterisked carbons into the correct axial/equatorial sites.
