Question

Quizplus · Accepted Answer

Proton transfer from an acid is characteristic of general acid catalysis, which lowers the free energy of a reaction's transition state. Nucleophilic catalysis involves the participation of a nucleophile, electrostatic catalysis involves the stabilization of transition states through electrostatic interactions, and general base catalysis involves proton abstraction by a base. Concerted acid-base catalysis involves the simultaneous involvement of both an acid and a base in the catalytic mechanism.
