For each of the following reactions, predict the major product(s), showing proper stereochemistry where appropriate. Write N.R. if no reaction occurs. Identify the type of substrate (1º, 2º, 3º, allylic, benzylic, aryl, vinyl) and give the type of mechanism by which each product is formed (Syl, Sy2, E, B). Assume the reaction is at room temperature if no temperature or heat symbol (A) is indicated. You may work in peer groups; if so, turn in just one copy with the...
