Phenol groups
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… WebPhenols are organic compounds which contain a hydroxyl (—OH) group attached to a carbon atom in a benzene ring. Their chemical behavior is very distinct from that of alcohols, because they are not capable of undergoing the same …
