Does phenol show tautomerism
WebDoes aldehyde show tautomerism? If an aldehyde possesses at least one hydrogen atom on the carbon atom adjacent to the carbonyl group, called the alpha (α) carbon, this hydrogen can migrate to the oxygen atom of the carbonyl group. As a result, a carbonyl compound with an α-hydrogen can exist in two isomeric forms, called tautomers. ... 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 e…
