Starting materials for the preperation of inorganic benzene is

Options

A. `B_2 H_6 + HN_3`
B. `BH_3 + NH_2 NH_2`
C. `B_2 H_6 + NH_3`
D. `BH_3 + NH_2 OH`

Answer

To solve the question regarding the starting materials for the preparation of inorganic benzene (borazine), we need to analyze the options given and identify the correct pair of reactants.

### Step-by-Step Solution:

1. **Understanding Borazine**:
- Borazine is often referred to as inorganic benzene due to its structural similarity to benzene. It has alternating boron and nitrogen atoms in its ring structure, similar to the carbon atoms in benzene.

2. **Identifying the Correct Reaction**:
- The question provides several options for starting materials. We need to assess which combination leads to the formation of borazine.

3. **Analyzing the Options**:
- **Option A**: \( B_2H_6 + HN_3B \) - This option is not commonly associated with borazine synthesis.
- **Option B**: \( H_3 + NH_2NH_2 \) - This does not provide the necessary boron and nitrogen framework.
- **Option C**: \( B_2H_6 + NH_3 \) - This is a known method for synthesizing borazine.
- **Option D**: \( BH_3 + NH_2OH \) - This does not lead to borazine.

4. **Conclusion**:
- The correct starting materials for the preparation of inorganic benzene (borazine) is **Option C: \( B_2H_6 + NH_3 \)**.
