Concept explainers
(a)
Interpretation: The given reaction is to be classified as either a proton transfer reaction or a reaction of electrophile and nucleophile. The movement of electrons is to be shown by curved arrows.
Concept introduction: Lewis acid accepts an electron pair. It acts as an electrophile Lewis base donates an electron pair. It acts as nucleophile. Conjugate base is formed by the loss of a proton from an acid while conjugate acid is formed by the gain of electron by a base.
