The correct Answer is:
To analyze the given statements, we can break down the information step by step. ### Step 1: Understanding Statement 1 - **Statement 1**: "Natural rubber is an elastomer." - **Explanation**: Natural rubber is indeed classified as an elastomer. Elastomers are polymers that exhibit elastic properties, meaning they can stretch and return to their original shape. Natural rubber, specifically polyisoprene, has these rubber-like properties due to its molecular structure. ### Step 2: Understanding Statement 2 - **Statement 2**: "The intermolecular forces of attraction are due to dipole-dipole interactions." - **Explanation**: This statement is misleading. While natural rubber does have some intermolecular forces, the primary forces at play are not dipole-dipole interactions. Instead, the intermolecular forces in natural rubber are primarily Van der Waals forces (or London dispersion forces), which are weaker than dipole-dipole interactions. Therefore, this statement is false. ### Conclusion - **Final Assessment**: - Statement 1 is **True**: Natural rubber is an elastomer. - Statement 2 is **False**: The intermolecular forces are not primarily due to dipole-dipole interactions. ### Final Answer - Statement 1 is true, and Statement 2 is false. ---
