I'm just getting stumped on how to go on this one. I'm supposed to draw the major organic product formed at each step. A) I figure the bromine is added but can't decide where. I think it would go on the propyl chain but am not sure. B) Second part I see as an E2 reaction forming a double bond wherever the bromine is removed from. C) Third part I thought those were were used to break a triple bond and insert a double bonded O as well as some H. But of course I've formed no triple bonds anywhere. So as you can see, I'm just all lost
