Which of the following statements correctly distinguishes natural rubber from gutta-percha based on — Polymers Chemistry Question

💡 Solution & Explanation

Natural rubber has an all-*cis* configuration at the double bonds, creating a bent structure that prevents close packing and results in a coiled, elastic amorphous solid. Gutta-percha has an all-*trans* configuration, allowing chains to pack closely into a highly crystalline, hard, and non-elastic material.
