No, glucose is not a simple covalent compound. Glucose is a complex molecule classified as a monosaccharide and belongs to the carbohydrate family. It has the chemical formula C6H12O6. Glucose is a carbohydrate because it consists of carbon, hydrogen, and oxygen atoms in specific ratios.
While glucose is made up of covalent bonds between its constituent atoms (carbon, hydrogen, and oxygen), it is not a simple covalent compound in the sense of a small molecule with only a few atoms. Glucose is a large, complex molecule with multiple carbon atoms arranged in a specific structure. It forms a ring structure in its most stable form and plays a crucial role in biological processes as an important energy source in living organisms.
