The correct answer is D. C3H8O3.
Glycerol is a simple polyol compound with the chemical formula C3H8O3. It is a colorless, odorless, viscous liquid that is miscible with water and ethanol. Glycerol is a major component of animal and vegetable fats and oils, and it is also produced industrially by the hydrolysis of fats and oils.
Glycerol is used in a variety of applications, including:
- Food and beverage industry: Glycerol is used as a humectant, stabilizer, and sweetener in a variety of foods and beverages.
- Cosmetics and personal care products: Glycerol is used as a moisturizer, emollient, and lubricant in cosmetics and personal care products.
- Pharmaceuticals: Glycerol is used as a solvent, excipient, and lubricant in pharmaceuticals.
- Industrial applications: Glycerol is used as a solvent, lubricant, and antifreeze in industrial applications.
Glycerol is a safe and non-toxic compound. However, it can be harmful if ingested in large amounts. Glycerol is also a potential carcinogen, but the risk of cancer from exposure to glycerol is considered to be low.
The other options are incorrect because they do not represent the chemical formula of glycerol. Option A, C2H5O2, is the chemical formula of ethanol. Option B, C3H7OH, is the chemical formula of propyl alcohol. Option C, C3H5OH, is the chemical formula of isopropyl alcohol.
