The correct Answer is:
To solve the given question, we need to analyze the reaction of the amino acid with nitrous acid (HNO2). The amino acid is represented as R-NH2-CH(COOH). ### Step-by-Step Solution: 1. **Identify the Reactant**: The reactant is an amino acid with the structure R-NH2-CH(COOH). Here, R represents a hydrocarbon chain or group, NH2 is the amino group, and COOH is the carboxylic acid group. 2. **Reaction with Nitrous Acid (HNO2)**: When an amino acid reacts with nitrous acid (HNO2), the amino group (NH2) is converted into a hydroxyl group (OH). This reaction is a characteristic reaction of primary amines. 3. **Write the Reaction**: The reaction can be represented as follows: \[ R-NH2-CH(COOH) + HNO2 \rightarrow R-OH-CH(COOH) + N2 + H2O \] In this reaction, the NH2 group is replaced by an OH group, and nitrogen gas (N2) and water (H2O) are produced as by-products. 4. **Identify the Product**: After the reaction, the product A will be R-OH-CH(COOH). This means that the amino acid has been converted into a hydroxy acid. 5. **Final Structure of Product A**: The final structure of product A can be represented as follows: \[ R-CH(OH)-COOH \] This indicates that the amino group has been replaced by a hydroxyl group, resulting in a hydroxy acid. ### Conclusion: The product A is a hydroxy acid with the structure R-CH(OH)-COOH.
