Diborane on hydrolysis gives

Options

A. `BC_3`
B. `H_3 BO_3`
C. `HBO_2`
D. `B_3 N_3 H_6`

Answer

To solve the question "Diborane on hydrolysis gives," we will follow these steps:

### Step 1: Understand the Reactants
Diborane is a chemical compound with the formula B₂H₆. It is known for its unique properties and reactivity, particularly with water (H₂O).

**Hint:** Identify the chemical formula of diborane and its reactivity with water.

### Step 2: Write the Hydrolysis Reaction
When diborane reacts with water, it undergoes hydrolysis. The reaction can be written as:
\[ \text{B}_2\text{H}_6 + 6 \text{H}_2\text{O} \rightarrow 2 \text{H}_3\text{BO}_3 + 3 \text{H}_2 \]

**Hint:** Remember that hydrolysis involves the reaction of a compound with water, leading to the formation of new products.

### Step 3: Identify the Products
From the reaction, we can see that diborane hydrolyzes to form:
1. Boric acid (H₃BO₃)
2. Hydrogen gas (H₂)

**Hint:** Focus on the products formed during the hydrolysis of diborane.

### Step 4: Balance the Reaction
To ensure the reaction is balanced, we check the number of atoms of each element on both sides:
- Boron (B): 2 on both sides
- Oxygen (O): 6 on both sides
- Hydrogen (H): 18 on both sides (6 from water and 12 from boric acid and hydrogen gas)

The reaction is balanced.

**Hint:** Always verify that the number of atoms for each element is the same on both sides of the equation.

### Conclusion
Thus, the final products of the hydrolysis of diborane (B₂H₆) are boric acid (H₃BO₃) and hydrogen gas (H₂).

### Final Answer
Diborane on hydrolysis gives **H₃BO₃ (boric acid) and H₂ (hydrogen gas)**.
