Each question contain statement-1 (Assertion) and statement-2 (Reason) Examine the statements carefully and work the correct answer according to the instruction given below :
Statement - 1 : Oxidation also occurs when decrease in electron density is observed.
Statement - 2 : Oxidation is gain of electro-positive element.

Options

A. If both the statements are True and Statement-2 is the correct explanation of the statement-1
B. If both the statements are True and statement-2 is not the correct explanation of statement-1
C. If statement-1 is true and statement-2 is False.
D. If statement-1 is false and statement-2 is True.

Answer

To solve the assertion-reason question, we need to analyze both statements carefully.

### Step 1: Analyze Statement 1
**Statement 1:** Oxidation also occurs when a decrease in electron density is observed.

- **Explanation:** Oxidation is defined as the loss of electrons or an increase in oxidation state. A decrease in electron density indicates that electrons are being removed or lost from an atom or ion. Therefore, this statement is true because a decrease in electron density corresponds to the process of oxidation.

### Step 2: Analyze Statement 2
**Statement 2:** Oxidation is the gain of an electro-positive element.

- **Explanation:** This statement is misleading. Oxidation typically refers to the loss of electrons or the increase in oxidation state, not the gain of an electro-positive element. In fact, oxidation is often associated with the loss of electro-negative elements or the gain of electro-positive elements. Thus, this statement is false.

### Conclusion
- **Final Assessment:**
- Statement 1 is true.
- Statement 2 is false.

Thus, the correct answer is that Statement 1 is true and Statement 2 is false.
