1. (2 points each) Complete each of the following reactions
by adding the missing part: either the starting compound, the
necessary reagents and conditions, or the final major product.
Indicate stereochemistry if it is specific.
2. (2 points) Identify the major product expected in each case and also identify the most likely mechanism by which it would be formed.
3. (2 points) Write a complete mechanism that explains the following reaction, in particular the stereochemistry. The final product is racemic, even if the original compound is optically active.
