Glycerol, C3H5(OH)3, is unusual in having three OH groups, one for each carbon atom. The OH group can reasonably be viewed as two thirds of a water molecule (H2O, or HOH), and this is responsible for the physical and chemical properties of the alcohols. It has this property mainly because of its polyol (three -OH) groups ability to form hydrogen bonds with water molecules. What strategies can be used to maximize the impact of a press release?
