- A benzene ring alters the reactivity of a neighboring group in the so-called “benzylic” position, similarly to how a double bond alters the reactivity of groups in the “allylic” position. Benzylic cations, anions, and radicals are all more stable than simple alkyl intermediates. a) Use resonance structures to show the delocalization of the positive charge, negative charge, and unpaired electron of the benzyl cation, anion, and radical.What is the reaction? cycloaddition A A B D [Single selection] A B D CO₂Me CO₂Me HPh HPh OH CO₂Me CO₂MeVhich of the following statements is incorrect? * 3 p 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.
