1) Draw the arrows to show bond formation and breaking for the following mechanisms and complete questions b, c, and d. Marking scheme is also provided. (9 marks total) a) All tails of arrows must start at electrons. The arrows must start in the middle of a sigma bond or at a lone pair (2 marks) Take % mark for each mistake until you reach zero. All heads of arrows must end at an atom. (2 marks) Take X mark for each mistake until you reach zero. b) Identify all nucleophiles, electrophiles, acids and bases by circling the word in the figure. (2 marks) Take X mark for each mistake until you reach zero. c) Identity each process as nucleophilic attack, loss of leaving group, proton transfer or carbocation rearrangement (circle in figure). (2 marks) Take X mark for each mistake until you reach zero. d) Label carbocations as primary, secondary or tertiary.
