The correct Answer is:
To solve the question regarding the statements about silicone polymers, we will analyze each statement step by step. ### Step 1: Analyze Statement 1 **Statement 1:** `R2SiCl2` is the starting material for a linear polymer of silicone. - **Explanation:** When `R2SiCl2` is hydrolyzed (reacted with water), it can form `R2Si(OH)2`. This compound can then further react with other `R2Si(OH)2` molecules to create a linear chain polymer. The hydroxyl groups (–OH) allow for the formation of bonds between the silicon atoms, leading to a linear structure. **Conclusion for Statement 1:** This statement is **correct**. ### Step 2: Analyze Statement 2 **Statement 2:** `R2SiCl2` is the starting material for a 3-D polymer of silicone. - **Explanation:** `R2SiCl2` primarily leads to the formation of linear polymers as explained in Statement 1. To create a 3-D network structure, a compound with more than two reactive sites (like `R3SiCl`) is generally required. Therefore, `R2SiCl2` cannot form a 3-D polymer. **Conclusion for Statement 2:** This statement is **incorrect**. ### Step 3: Analyze Statement 3 **Statement 3:** `R3SiCl` is the starting material for a 3-D polymer of silicone. - **Explanation:** `R3SiCl` has three alkyl groups attached to silicon, which allows it to react with three hydroxyl groups when hydrolyzed. This leads to the formation of a 3-D network structure, as each silicon atom can bond with multiple other silicon atoms, creating a cross-linked polymer. **Conclusion for Statement 3:** This statement is **correct**. ### Final Summary of Statements - **Statement 1:** Correct - **Statement 2:** Incorrect - **Statement 3:** Correct
