Phenol nucleophilicity
Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and water at phenol to water mass ratios of ~2.6 and higher are possible. The sodium salt of phenol, sodium phenoxide, is far more water-soluble. Phenol is a weak acid. In aqueous solution in the pH range ca. 8 - 12 it is in equ… Weba nucleophile is a good nucleophile. Nucleophilicity (nucleophile strength) is a kinetic phenomenon, measured by comparing rates of reaction. Good nucleophiles have fast …
