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 find the starting materials for the preparation of inorganic benzene, we can follow these steps:

### Step 1: Identify the target compound
The target compound is inorganic benzene, which is also known as borazine. Borazine has a structure similar to benzene but consists of alternating boron and nitrogen atoms.

### Step 2: Understand the structure of borazine
Borazine has the formula B3N3H6. It consists of three boron (B) atoms and three nitrogen (N) atoms arranged in a cyclic structure with hydrogen (H) atoms attached to each boron and nitrogen atom.

### Step 3: Determine the starting materials
To synthesize borazine, we need to consider the elements that can combine to form it. The two primary starting materials are:
- **Diborane (B2H6)**: This compound provides the boron atoms required for the formation of borazine.
- **Ammonia (NH3)**: This compound provides the nitrogen atoms necessary for the synthesis.

### Step 4: Reaction mechanism
When diborane reacts with ammonia, it leads to the formation of borazine. The boron atoms from diborane and the nitrogen atoms from ammonia combine to form the boron-nitrogen framework of borazine.

### Conclusion
Thus, the starting materials for the preparation of inorganic benzene (borazine) are diborane (B2H6) and ammonia (NH3).

### Final Answer
**Starting materials for the preparation of inorganic benzene are diborane (B2H6) and ammonia (NH3).**
