`{:(F_2+dil.NaOHto A+B+C),(F_2+conc.NaOHtoA+D+C):}`
Which is correct?

Options

A. A is NaF
B. B is `O_2`
C. C is `H_2O`
D. D is `OF_2`

Explanation

To solve the question regarding the reactions of fluorine (F2) with dilute and concentrated sodium hydroxide (NaOH), we will analyze both reactions step by step.

### Step 1: Reaction of F2 with Dilute NaOH
1. **Write the reaction**:
\[ F_2 + \text{dil. NaOH} \rightarrow A + B + C \]
2. **Identify the products**:
The products formed when F2 reacts with dilute NaOH are sodium fluoride (NaF), oxygen difluoride (OF2), and water (H2O).
- A = NaF
- B = OF2
- C = H2O

### Step 2: Reaction of F2 with Concentrated NaOH
1. **Write the reaction**:
\[ F_2 + \text{conc. NaOH} \rightarrow A + D + C \]
2. **Identify the products**:
The products formed when F2 reacts with concentrated NaOH are sodium fluoride (NaF), oxygen (O2), and water (H2O).
- A = NaF
- D = O2
- C = H2O

### Step 3: Compare the Products
- From both reactions, we can summarize:
- Common product A = NaF
- Common product C = H2O
- Unique product B from dilute NaOH = OF2
- Unique product D from concentrated NaOH = O2

### Conclusion
- The correct identification of products is:
- From the reaction with dilute NaOH: A = NaF, B = OF2, C = H2O
- From the reaction with concentrated NaOH: A = NaF, D = O2, C = H2O

### Final Answer
- The correct identification of products is:
- A = NaF
- B = OF2
- C = H2O
- D = O2
