Statement-1: With non-metals covalent hydrides are formed.
Statement-2: For covalent hydrides electronegativity difference should be less.

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 given statements, we will break down each statement and evaluate its correctness.

### Step 1: Evaluate Statement 1
**Statement 1:** "With non-metals, covalent hydrides are formed."

- **Explanation:** Covalent hydrides are compounds formed when hydrogen bonds with non-metals through covalent bonds. In these compounds, hydrogen shares its electron with the non-metal, leading to the formation of a covalent bond. Common examples of covalent hydrides include ammonia (NH₃), water (H₂O), hydrogen fluoride (HF), and borane (BH₃).

**Conclusion for Step 1:** Statement 1 is correct.

### Step 2: Evaluate Statement 2
**Statement 2:** "For covalent hydrides, electronegativity difference should be less."

- **Explanation:** The formation of covalent bonds occurs when the electronegativity difference between the two atoms (in this case, hydrogen and the non-metal) is small. If the electronegativity difference is large, the bond tends to be ionic rather than covalent. Therefore, for a covalent hydride to form, the electronegativity difference between hydrogen and the non-metal must be low, indicating that they can share electrons rather than one atom completely transferring an electron to the other.

**Conclusion for Step 2:** Statement 2 is also correct.

### Step 3: Determine the Relationship Between the Statements
- Since both statements are correct and Statement 2 provides a valid explanation for Statement 1, we conclude that Statement 2 is indeed the correct explanation for Statement 1.

### Final Conclusion
Both Statement 1 and Statement 2 are true, and Statement 2 is the correct explanation for Statement 1.

### Summary of the Solution
- **Statement 1:** True (Covalent hydrides are formed with non-metals)
- **Statement 2:** True (Electronegativity difference should be less for covalent hydrides)
- **Conclusion:** Both statements are true, and Statement 2 is the correct explanation for Statement 1.
