What about the second step in the electrophilic addition of HCl to an alkene-the reaction of chloride ion with the carbocation intermediate? Is this step exergonic or endergonic? Does the transition state for this second step resemble the reactant (carbocation) or the product (alkyl chloride)? Make a rough diagram of what the transition state may look like?

Which of the following statements is incorrect concerning addition reactions of alkenes? (X = halogen) O The electron-rich n-bond of the alkene acts as a nucleophile. Carbocation rearrangement can occur for the addition of HX to an alkene. Carbocation rearrangement can occur for the hydration (H*/H20) of alkenes. Carbocation rearrangement can occur for the addition of X2 to an alkene. Addition of HX proceeds via both syn and anti addition.
Question 2 Which statement is consistent with the Hammond postulate? O the transition state of an endothermic reaction step structurally resembles the reactant. O it is used to assign the E/Z stereochemistry of alkenes. the less stable carbocation intermediate is formed in electrophilic additions to alkenes. O in additions of HX to alkenes, the H adds to the less substituted alkene carbon and the X adds to the more substituted alkene carbon. O the transition state of an exothermic reaction step structurally resembles the reactant.
