Phenol characteristics
WebPhenol has a molar mass of 94.11124 g mol −1 and is a pale to pink solid or dense liquid with a typically sweet tar-like odor. Its solubility in water is 87 g l −1 at 25 °C. Its density at … In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (−OH) bonded directly to an aromatic hydrocarbon group. The simplest is phenol, C 6H 5OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule.
