The correct Answer is:
To analyze the statements provided in the question, we will evaluate each statement step by step. ### Step 1: Evaluate Statement 1 **Statement 1:** Nylon fibers are stronger than terylene fibers. - **Explanation:** Nylon is known for its high tensile strength and durability. It is a synthetic polymer that exhibits strong intermolecular forces due to hydrogen bonding between its polymer chains. This results in nylon fibers being very strong and resistant to breaking, making them suitable for applications such as ropes and climbing gear. ### Step 2: Evaluate Statement 2 **Statement 2:** Intermolecular forces of attraction in terylene are hydrogen bonding. - **Explanation:** Terylene, also known as polyester, primarily exhibits dipole-dipole interactions rather than hydrogen bonding. The intermolecular forces in terylene are weaker compared to the hydrogen bonding present in nylon. This is a crucial point because the strength of the fibers is influenced by the type of intermolecular forces present. ### Step 3: Conclusion - **Correctness of Statements:** - Statement 1 is **True**: Nylon fibers are indeed stronger than terylene fibers due to the presence of stronger intermolecular forces (hydrogen bonding). - Statement 2 is **False**: The intermolecular forces in terylene are not hydrogen bonding; they are dipole-dipole interactions. ### Final Answer Based on the evaluations: - Statement 1 is true. - Statement 2 is false. Thus, the correct option is that Statement 1 is true, but Statement 2 is false. ---
