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. A Moving to another question will save this response. 80 F3 54 $ 4 000 000 F4 % 5 F5 6 MacBook Air F6 & 7 ao F7 8 DII F8 ( 9 F9
