This species is transferred intramolecularly in ESIPT chromophores.
This species is transferred intramolecularly in ESIPT chromophores. 1,8 bis-dimethy-amino-napthalene serves as a "sponge" for this species. The transfer of this species is the fastest reaction in organic chemistry, which is why carbon nucleophiles are completely unusable in its presence. The transfer of this species to the ketone oxygen is one way of (*) catalyzing keto-enol tautomerism. The "hopping" of this species generates the eigen and the zundel cations in the Grotthus mechanism. Solvents that are polar and lack this species are commonly used in SN2 reactions. The negative log of the concentration of this species gives the pH. For 10 points, name this species, which Bronstead-Lowry acids donate.
