The correct Answer is:
To solve the question, we need to understand the structure of glycerol and what happens when one of its hydrogen atoms in the -OH group is replaced by phosphoric acid. ### Step-by-Step Solution: 1. **Identify the Structure of Glycerol:** - Glycerol, also known as glycerin, is a simple polyol compound. Its chemical formula is C3H8O3. It has three hydroxyl (-OH) groups, which are responsible for its alcohol properties. 2. **Understand Phosphoric Acid:** - Phosphoric acid has the chemical formula H3PO4. Its structure consists of a phosphorus atom bonded to four oxygen atoms, one of which is bonded to a hydrogen atom (making it an acid). 3. **Replacement of Hydrogen Atom:** - In the question, we are instructed to replace one of the hydrogen atoms in the -OH group of glycerol with a phosphoric acid molecule. This means that instead of having a hydroxyl group (-OH), we will have a phosphate group (-OPO3H2). 4. **Resulting Compound:** - When one -OH group of glycerol is replaced by a phosphoric acid group, the resulting compound is known as a phospholipid. Phospholipids are a major component of cell membranes and are classified as a type of lipid. 5. **Conclusion:** - Therefore, the compound formed when one of the hydrogen atoms of the -OH groups in glycerol is replaced with phosphoric acid is called a **phospholipid**. ### Final Answer: The compound is called a **phospholipid**. ---
