- Are the products of the given reaction correct? Why or why not?arrow_forwardThe question below asks why the products shown are NOT the correct products. I asked this already, and the person explained why those are the correct products, as opposed to what we would think should be the correct products. That's the opposite of what the question was asking. Why are they not the correct products? A reaction mechanism for how we arrive at the correct products is requested ("using key intermediates"). In other words, why is HCl added to the terminal alkene rather than the internal alkene?arrow_forwardMy question is whether HI adds to both double bonds, and if it doesn't, why not?arrow_forward
