Document Summary
2. 222 introductory organic chemistry ii term test 1. This is a 2-hour test, marked out of 50 points total. If more space is required you may use the backs of the exam pages but be sure to indicate that you have done so. A table of spectroscopic data is attached at the end of the exam. (8 marks) provide a detailed stepwise mechanism for the following friedel-crafts acylation reaction, showing all the steps. Make sure your mechanism clearly illustrates why the major product has the para regiochemistry. O cation is stabilized by donation of oxygen lone pairs. Page 2 of 7 (7 marks) provide a detailed, stepwise mechanism for the following transformation. Give the product you predict would be formed by the second reaction sequence: t-butyl chloride. Fecl3: fuming h2so4, fuming h2so4, t-butyl chloride. In the first sequence, friedel-crafts alkylation occurs before sulfonation. The product of the first step is t-butylbenzene.
