Statement-1: Silicones are used as high class industrial insulators.
Statement-2: Silicones are large covalent solids so bad conductors of electricity.

Options

A. Statement-1 is true, statement-2 is true, statement-2 is a correct explanation for statement-1
B. Statement-1 is true, statement-2 is true, statement-2 is not correct explanation for statement-1
C. Statement-1 is true, statement-2 is false
D. Statement-1 is false, statement-2 is true

Answer

To analyze the statements provided in the question, we will break down the reasoning step by step.

### Step 1: Understand the nature of silicones
Silicones are synthetic polymers made up of silicon, oxygen, carbon, and hydrogen. They are known for their high thermal stability and electrical insulating properties.

**Hint:** Consider the composition and structure of silicones to understand their properties.

### Step 2: Evaluate Statement 1
**Statement 1:** "Silicones are used as high-class industrial insulators."

- **Analysis:** Silicones are indeed used as insulators in various industrial applications due to their excellent electrical insulating properties. They do not conduct electricity effectively, making them suitable for use in electrical insulation.

**Hint:** Think about the properties of materials that make them suitable for insulation.

### Step 3: Evaluate Statement 2
**Statement 2:** "Silicones are large covalent solids so bad conductors of electricity."

- **Analysis:** This statement is also true. Silicones are large covalent structures, which means they do not have free-moving charged particles (like ions) that are required for electrical conductivity. As a result, they are poor conductors of electricity.

**Hint:** Recall the difference between ionic and covalent bonding and how it affects conductivity.

### Step 4: Determine the relationship between the statements
Both statements are true, and Statement 2 provides a correct explanation for Statement 1. The reason silicones are used as insulators (Statement 1) is due to their nature as large covalent solids that are poor conductors of electricity (Statement 2).

**Hint:** Look for how one statement supports or explains the other.

### Step 5: Conclusion
Both statements are true, and Statement 2 is the correct explanation for Statement 1. Therefore, the correct answer is that both statements are true, and Statement 2 explains Statement 1.

**Final Answer:** Both Statement 1 and Statement 2 are true, and Statement 2 is the correct explanation for Statement 1.
