1. (16 pts) Give structures for intermediate A and product B. 2. (1B pts) Give structures for intermediates A and B, and for product C. 3. (18pts) Give a reasonable stepwise mechanism for the following reaction: 4. (16 pts) Show one resonance structure of the preferred intermediate, and the product, for the following reaction. 5. (16 pts) Give a reasonable reaction sequence for the following transformation. A sequence 6. (15 pts) Predict the major product of this reaction, showing key intermediates. Note: p means, you do not need to show your arrow-pushing (though feel free; it may help), but you tol SO3H is para-toluenesulfonic acid, or 4H3CC6H3SO2OH2 a crystalline strong acid. need to show each step clearly: any intermediates, praducts, and byproducts. We have not studied organolithium reagents yet, but think of them as carbanions bound to L+and you'll have what you need. First carbocation-like intermediate A: Second carbocation-like intermediate B
