Phenolic alcohol

WebPhenethyl alcohol, or 2-phenylethanol, is the organic compound that consists of a phenethyl group (C 6 H 5 CH 2 CH 2) attached to OH.It is a colourless liquid that is slightly soluble in water (2 ml/100 ml H 2 O), but miscible with most organic solvents. It occurs widely in nature, being found in a variety of essential oils.It has a pleasant floral odor. WebCompounds like alcohols and phenol which contain an -OH group attached to a hydrocarbon are very weak acids. Alcohols are so weakly acidic that, for normal lab purposes, their acidity can be virtually ignored. However, phenol is sufficiently acidic for it to have recognizably acidic properties - even if it is still a very weak acid.
