8.1 Give the structure and name of the product that would be obtained from the ionic addition of IBr to propene. Answer: IBrIBrBrI8.3 Provide mechanistic explanations for the following observations：（a）The addition of hydrogen chloride to 3-methyl-1-butene produces two products：2-chloro-3-methylbutane and 2-chloro-2-methylbutane. (b) The addition of hydrogen chloride to 3,3-dimethyl-1-butene produces two products: 3-chloro-2,2-dimethylbutane and 2-chloro-2,3-dimethylbutane. (The first explanations for the course of both of these reactions were provide by F. Whitmore; see Section 7.7A.) Answer: (a)step 1: H+C+; C+C+Because theC+much more stable then the C+step 2: C++ Cl-Cl; C++ Cl+MeCl
