A Chemical Education Tool for Evaluation of pKa of Proton Dissociation Equilibrium of Any Substituted Benzene (XC6H5)
The sturdy empirical relation, ρ = (two.four)(two–i), between the Hammett ρ for proton dissociation of many acids and the quantity, “i”, of atoms between the ionizable hydrogen and the ring carbon (Andrew Williams, Absolutely free Energy Associations in Natural and Bioorganic Chemistry, Royal Culture of Chemistry, Cambridge, 2003, p. seventy […]
