With cyclohexanes you must consider the orientation of the leaving group and the acidic hydrogen. 8) Draw the two cyclohexane conformations using the diagram below and label the most stable conformation. Use the diagram below and add the groups or atoms to each labeled carbon. b) Draw the mechanism for the E2 reaction. c) Draw the major E2 product d) Only one E2 product is formed, why? *If you complete the question on a separate piece of paper, you must reproduce the drawing below, or marks will be taken off.* 8 Marks 2 marks one mark for each chair conguration - Must add atoms and groups to the gures below. 1 mark for identifying most stable conformation 3 marks for drawing correct arrows to show the mechanism of the E2 reaction.
