The correct Answer is:
To solve the question, we need to identify the polymer that has isoprene as its repeating unit. Let's break down the solution step by step: ### Step-by-Step Solution: 1. **Identify the Structure of Isoprene**: - Isoprene is a diene with the chemical formula \( CH_2=C(CH_3)-CH=CH_2 \). It consists of a five-carbon chain with two double bonds. 2. **Understand the Concept of Monomers and Polymers**: - A monomer is a small molecule that can join together with other similar molecules to form a polymer. In this case, isoprene acts as the monomer. 3. **Polymerization of Isoprene**: - When multiple isoprene molecules undergo polymerization, they link together to form a larger macromolecule. This process involves the formation of covalent bonds between the isoprene units. 4. **Identify the Resulting Polymer**: - The polymer formed from the polymerization of isoprene is known as polyisoprene. 5. **Relate Polyisoprene to Natural Rubber**: - Polyisoprene is commonly known as natural rubber. It is a significant material used in various applications, including tires, footwear, and other rubber products. 6. **Conclusion**: - Therefore, the repeating unit in the polymer is polyisoprene, which is also referred to as natural rubber. ### Final Answer: Isoprene is the repeating unit in **natural rubber (polyisoprene)**. ---
