The use of Grignard reagents in
multi-step synthesis is widely employed. For each of the reaction
sequences below, draw the major organic product that would be
present after each reaction of the sequence. No mechanisms, no
explanations, just draw the products (in total, 14 reaction
products A to N are required). You may have to consult your lecture
material and/or the textbook to solve some of these problems
