Key Terms: Organic chemistry, Alcohol, Phenol, functional groups, compound. The resulting hydrate (structure shown below the aldehyde) meets both the requirements stated above, and is further oxidized by the same chromate ester mechanism. Phenols are much more acidic than alcohols because the negative charge in the phenoxide ion is not localized on the oxygen atom, as it is in an alkoxide ion, but is delocalized-it is shared by a The lone pair on oxygen O-H in phenol is being shared with benzene ring through resonance. Phenol is an aromatic compound that is As a result, it can readily donate electrons to an oxidising agents. A phenol always involves a benzene (type) ring, and often the Notice that electron withdrawing groups on an alcohol increase the acidity by stabilizing the alkoxide formed. Difference Between Alcohol and Phenol Explanation. It is readily soluble in alcohol and mildly soluble in water. boiling points) and chemical behavior. e.g. Phenol on reaction with neutral FeCl3 gives purple colour whereas alcohols do not give purple colour. Structure Organic compounds (phenols) contain hydroxyl groups (-OH) attached to their carbon atoms, forming aromatic rings. INTRODUCING PHENOL. Phenolphthalein acts as an indicator in acid-base titrations.
