Consider the following statements
I.The electronegativity of fluorine is more than that of chlorine
II.The electronegativity of nitrogen is more than that of oxygen
Choose the correct option

Options

A. only I
B. Only II
C. I and II
D. none of these

Answer

To solve the question, we need to evaluate the two statements regarding electronegativity:

1. **Statement I**: The electronegativity of fluorine is more than that of chlorine.
2. **Statement II**: The electronegativity of nitrogen is more than that of oxygen.

### Step-by-step Solution:

**Step 1: Analyze Statement I**
- Electronegativity is the ability of an atom to attract electrons in a chemical bond.
- Fluorine (F) is known to have the highest electronegativity of all elements, with a value of approximately 4.0 on the Pauling scale.
- Chlorine (Cl) has a lower electronegativity, approximately 3.0.
- Since 4.0 (F) > 3.0 (Cl), **Statement I is correct**.

**Step 2: Analyze Statement II**
- Now, let's look at the electronegativity values for nitrogen (N) and oxygen (O).
- Nitrogen has an electronegativity of about 3.0, while oxygen has a higher electronegativity of about 3.5.
- Since 3.0 (N) < 3.5 (O), **Statement II is incorrect**.

**Step 3: Conclusion**
- Based on the analysis:
- Statement I is correct.
- Statement II is incorrect.
- Therefore, the correct option is that only Statement I is true.

### Final Answer:
The correct option is that **only Statement I is correct**.
