Diborane upon hydrolysis gives

Options

A. boric anhydride
B. metaboric acid
C. orthoboric acid
D. boron oxide

Answer

To determine the product of diborane (B2H6) upon hydrolysis, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compound**: Diborane is represented by the chemical formula B2H6. It is known to be a 3-center, 2-electron compound.

2. **Understand Hydrolysis**: Hydrolysis refers to the reaction of a compound with water (H2O). In this case, we are interested in how diborane reacts when it comes into contact with water.

3. **Write the Reaction**: When diborane reacts with water, it can be represented by the following chemical equation:
\[ B_2H_6 + 6 H_2O \rightarrow 2 H_3BO_3 + 3 H_2 \]
Here, H3BO3 is orthoboric acid.

4. **Identify the Products**: From the balanced equation, we see that the products of the reaction are:
- Orthoboric acid (H3BO3)
- Hydrogen gas (H2)

5. **Conclusion**: The primary product of diborane upon hydrolysis is orthoboric acid (H3BO3).

### Final Answer:
Diborane upon hydrolysis gives orthoboric acid (H3BO3).
