True or false? Alcohol molecules can form hydrogen bonds …

WebPhenol has a high boiling point because the -OH group allows phenol molecules to hydrogen bond with other phenol molecule. Phenol is slightly soluble in water because the -OH group can form hydrogen bonds with water molecules. In water, the -OH group of phenol ionizes slightly, which makes it a weak acid. WebJun 21, 2015 · The strong hydrogen bond between ethanol and water makes the largest contribution to the relative energies of the structures.
