PART II: REACTIONS: Here is another different" question. Pretend you have been asked by me to put together a bunch of one-step reactions WITH starting materials (your choice), reagents and answers to help me with writing a final exam. For example: let's say I ask you to give an example of a free radical chlorination with a non-cyclic compound. Below would be your answer. As I am pretty sure you can figure out, there are millions of...
