3. Occasionally when performing $S_N1$ style substitution reactions unexpected products can form. It's as if some mysterious force can simply pluck off an atom or group of atoms and attach it somewhere else on a whim! Actually, there is a very logical explanation for this phenomena, but I need you to remind me what it is. So, for the reaction depicted below, (a) using curved arrow notation, please explain the formation of all products via a detailed, step-wise mechanism. (b) In a single sentence, please explain what was the driving force behind making this unexpected product? (10 pts) HO H-CI CI $H_2O$ (a) (b)

Without evaluating the integral; Set up the integral that represents (4.1) the volume of the surface that lies below the surface $z = 4xy - y^3$ and above the region D in the xy-plane, where D is bounded by $y = 0$, $x = 0$, $x + y = 2$ and the circle $x^2 + y^2 = 4$. (4.2) the volume inside the paraboloid $z = 16 - x^2 - y^2$, and outside the cylinder $x^2 + y^2 = 9$, and above the xy-plane.
