Answer: For instance, the alcohol glycerol has three hydroxyl groups. Because it contains three separate kinds of hydroxyls or alcohol, glycerol is a trihydric alcohol. Fats and oils include glycerin, a viscous liquid with a sweet flavour. In coconut and olive oil, it is the predominant triglyceride. Additionally, glycerol has certain chemical characteristics that make it more practical to employ when oil fails.
Glycerol is a viscous, hygroscopic liquid that is colourless, odourless, and non-toxic in nature. It also has a pleasant flavour. It is soluble in both water and ethyl alcohol but not in ether.
