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

To answer the questions below use the following information: Cyanohydrins are important intermediates in the synthesis of c-hydroxycarboxylic acids from ketones and aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid. Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin is treated with aqueous base the original carbonyl compound is isolated OH CHCOOH HO CN OBU H HCEN H NAOH H20...
