Assertion: Metals are generally good conductors of electricity
Reason: Electrical conductivity of metals is due to Schottky type of defects

Options

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

Answer

To solve the question regarding the assertion and reason provided, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
**Assertion:** Metals are generally good conductors of electricity.

- **Explanation:** This statement is true. Metals are known for their ability to conduct electricity efficiently. This is primarily due to the presence of free-moving electrons (also known as conduction electrons) within the metallic structure. These electrons are not bound to any particular atom and can move freely, allowing electric current to flow easily through the metal.

### Step 2: Analyze the Reason
**Reason:** Electrical conductivity of metals is due to Schottky type of defects.

- **Explanation:** This statement is false. While defects in a crystal lattice can affect electrical properties, Schottky defects specifically refer to vacancies where both cations and anions are missing from the lattice in ionic solids. In metals, electrical conductivity is primarily due to the presence of free electrons, not defects like Schottky defects. Therefore, the reason provided does not accurately explain the assertion.

### Step 3: Conclusion
- The assertion is true, while the reason is false. Therefore, the correct option is that the first statement is true and the second statement is false.

### Final Answer:
The assertion is true, and the reason is false.
