The Correct Option is D
Solution and Explanation
Corrosion is the degradation of metals due to chemical reactions with environmental elements, often oxygen or water. To prevent corrosion, the surface of metals is typically coated with protective substances.
- Phenol: This compound is not typically used for corrosion protection. It is an aromatic alcohol used in various chemical processes.
- Benzene: Benzene is a solvent and is not used for coating metals to prevent corrosion.
- Acetone: Acetone is a solvent and has no role in protecting metals from corrosion.
- Bisphenol: Bisphenol is used in the production of protective coatings like epoxy resins, which are used to prevent corrosion of metallic surfaces. Therefore, it is the correct answer.
- Nitrophenol: This compound is not used for corrosion protection and has other industrial applications.
Thus, the correct answer is (D) Bisphenol, as it is used in the preparation of protective coatings for metals.
