Solution: The reaction coordinate diagram below is an example of the application of Hammond postulate to carbocation formation in an SN1 reaction. Based on the reaction coordinate diagram below, which of the following statements is FALSE? A. The relative stabilities of the carbocation decreases in the following order: 3o > 2o > 1o B. The transition state shifts towards the reactant with increasing carbocation stability. C. The transition state become more stable as the reaction becomes less endothermic. D. The most stable transition state resembles the product more than any other transition state.
