Borazine is the product of reaction between

Options

A. `B_(2)H_(6)`
B. `NH_(3)`
C. `BF_(3)`
D. `BCl_(3)`

Answer

To determine the reaction that produces borazine, we need to analyze the given options and identify the correct reactants. Borazine is a compound with the formula B3H6N3.

### Step-by-Step Solution:

1. **Identify the Reactants**: The question provides four options: B2H6 (diborane), NH3 (ammonia), BF3 (boron trifluoride), and BCl3 (boron trichloride). We need to find which two of these react to form borazine.

2. **Understanding Borazine Formation**: Borazine is known to be formed from the reaction of diborane (B2H6) and ammonia (NH3). This is a well-documented reaction in inorganic chemistry.

3. **Write the Reaction**: The reaction can be written as follows:
\[ B_2H_6 + 6 NH_3 \rightarrow B_3H_6N_3 + 6 H_2 \]
This indicates that diborane reacts with ammonia to produce borazine and hydrogen gas.

4. **Balancing the Reaction**:
- On the left side, we have 2 boron atoms from B2H6 and 6 nitrogen atoms from NH3.
- On the right side, borazine contains 3 boron atoms and 3 nitrogen atoms.
- To balance the boron, we can adjust the coefficients:
\[ 3 B_2H_6 + 6 NH_3 \rightarrow 2 B_3H_6N_3 + 6 H_2 \]
- This gives us the balanced equation.

5. **Conclusion**: From the analysis, we conclude that borazine is formed from the reaction between diborane (B2H6) and ammonia (NH3). Therefore, the correct answer is:
- **B2H6 and NH3**.
