Draw the structures of the organic products in each reaction of the following two-step synthesis. (Hint: The nucleophilic amine attacks the electrophilic carbonyl carbon, and the resulting intermediate undergoes a proton shift and dehydration. Recall what is eliminated in a dehydration process. The second step is a reduction reaction; the reducing agent is NaBH3CN (or H2, metal catalyst). The aromatic ring is unaffected by these reagents. Look at the product of the first reaction and consider what can be easily reduced.)

Draw a structural formula for the major organic product of the following reaction:Electrophilic addition of HBr to alkenes yields a bromoalkane. The reaction begins with an attack on the hydrogen of the electrophilic HBr by the electrons of the double bond to give a carbocation. This step follows Markovnikov's rule with the electrophilic H atom adding to the sp2 carbon containing the most hydrogens, leading to the formation of the most stable carbocation (1° < 2° < 3°). If possible, a...

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
