Let's assume you have a mixture of equal parts benzoic acid, sand and toluene that are intimately mixed together (the crude material is a mixture of solid and liquid). Propose a procedure to separate these three components using any of the chemicals commonly available (you've used all of the "common" chemicals in the lab by now) in the organic chemistry...

Please explain to me the answer: Why is structure 2 correct? The answer says: " compound 2 is lesss symmetrical, and permits two additional products and two Sn2 substitution products." But it still does not make sense to me. (structure two is the one on the right, numbered as 2) 4 (30 points). Once again, you have a bottle containing...
