The correct Answer is:
To solve the question, we need to analyze both statements carefully and determine their validity. ### Step-by-Step Solution: 1. **Understanding Statement 1**: - **Statement 1**: "Soap and detergent are macromolecular colloids." - **Analysis**: Macromolecular colloids are formed by large molecules that are typically larger than 1 nanometer and can exist as single entities. However, soaps and detergents are not classified as macromolecular colloids; they are better categorized as associated colloids. This is because they consist of aggregates of smaller molecules (micelles) that form when soap or detergent molecules cluster together in a solution. 2. **Understanding Statement 2**: - **Statement 2**: "Soap and detergent are molecules of large size." - **Analysis**: This statement is true. Soap and detergent molecules have long hydrophobic (water-repelling) hydrocarbon chains, which contribute to their larger size. For example, a common soap molecule like sodium stearate (C15H31COO⁻) has a long hydrocarbon chain, making it relatively large compared to simple small molecules. 3. **Conclusion**: - **Final Evaluation**: - Statement 1 is **false** because soaps and detergents are associated colloids, not macromolecular colloids. - Statement 2 is **true** because soaps and detergents are indeed large-sized molecules. - Therefore, the correct answer is that Statement 1 is false and Statement 2 is true. ### Answer: - **Statement 1**: False - **Statement 2**: True - The correct option is that Statement 1 is false and Statement 2 is true.
