. Which of the following statements is incorrect?   Hammond-Leffler Postulate states that there is a strong resemblance between the transition state and the product in an endothermic reaction.   Hammond-Leffler Postulate states that there is a strong resemblance between the transition state and the reactants in an exothermic reaction.   The presence of more electron-donating alkyl groups ineffectively delocalize the positive charge in an organic molecule, making it less stable.   The dehydration of primary alcohol proceeds via E2 mechanism.   All of the above
