Oh... okay.
Sorry then.
I did try, for the record, but I didn't say that I guess. I drew the structural formula and tried to figure out what things I could change where, but when it came down to it, I was just taking shots in the dark by drawing things on each of the carbons with no apparent reason. My original guess was B, because I thought maybe the OH would be stolen by the "acid" to form water, and maybe a double bond would form. But that didn't sound right because I've never heard of that occuring before except for condensation and hydrolysis things, and if that were what would happen, they would have just said acid and not mentioned the salt (which I guess is an oxidizer) I also realized that answer would be wrong because it would just not make sense to suddenly lose a hydrogen on the other side. Suffice to say, I was unsure of what I was doing. I kind of thought it might have been like using a permanganate salt to oxidize it and do something like I've seen in an example of, but I couldn't remember what exactly was going on. (which PRIYA explained for me very well)
I'm operating off of about 10 example reactions I've seen written. O-chem isn't in my text book, because my class hardly covers it, yet I'm supposed to know some basic O-chem for a test I will be taking in a month or two.
