Statement-II : `Zn` is transition metal according to electronic theory

Options

A. Statement-I is True, Statement-II is True, Statement-II is a correct explanation for Statement-I
B. Statement-I is True, Statement-II is True, Statement-II is NOT
a correct explanation for Statement-I
C. Statement-I is True, Statement-II is False.
D. Statement-I is False, Statement-II is True.

Answer

To solve the question, we need to analyze both statements and determine their validity, as well as the relationship between them.

### Step-by-Step Solution:

1. **Analyzing Statement-I**:
- Statement-I states that in the extraction of silver (Ag), the complex `Na[Ag(CN)₂]` is reacted with zinc (Zn).
- This is true because the complex `Na[Ag(CN)₂]` is a soluble complex of silver in cyanide, and it can be reduced to metallic silver (Ag) by using zinc as a reducing agent.

2. **Chemical Reaction**:
- The reaction can be represented as follows:
\[ 2 \text{Na[Ag(CN)}_2] + \text{Zn} \rightarrow 2 \text{Ag} + \text{Na}_2\text{Zn(CN)}_4 \]
- Here, zinc reduces the silver ion in the complex to form solid silver and a new complex with zinc.

3. **Analyzing Statement-II**:
- Statement-II claims that zinc (Zn) is a transition metal according to electronic theory.
- This statement is false. According to the definition of transition metals, they are elements that have partially filled d-orbitals. Zinc has the electronic configuration of \([Ar] 3d^{10} 4s^2\), which means its d-orbitals are fully filled (10 electrons in the 3d subshell), and thus it does not qualify as a transition metal.

4. **Conclusion**:
- Statement-I is true, while Statement-II is false. Therefore, the correct option is that Statement-I is true and Statement-II is false.

### Final Answer:
- **Statement-I**: True
- **Statement-II**: False

The correct option is that Statement-I is true and Statement-II is false.
