Number of hydroxy group attached to Boron in Borax are

Options

A. Four
B. Five
C. Six
D. Ten

Answer

To determine the number of hydroxy groups attached to boron in borax, we can follow these steps:

### Step 1: Understand the Chemical Formula of Borax
Borax is chemically represented as Na₂B₄O₇·10H₂O. This indicates that borax contains boron (B), oxygen (O), sodium (Na), and water molecules.

**Hint:** Look for the chemical formula to identify the components of the compound.

### Step 2: Analyze the Structure of Borax
The structure of borax consists of boron atoms connected by oxygen atoms. In the case of borax, there are four boron atoms in the structure.

**Hint:** Visualize or draw the structure of borax to see how the boron and oxygen atoms are arranged.

### Step 3: Identify Hydroxy Groups
A hydroxy group is represented as -OH. In the structure of borax, each boron atom is bonded to hydroxyl groups.

**Hint:** Count the -OH groups that are directly attached to the boron atoms in the structure.

### Step 4: Count the Hydroxy Groups
From the structure of borax, we can see that there are four hydroxyl groups (-OH) attached to the boron atoms.

**Hint:** Make sure to count all the -OH groups that are directly connected to the boron atoms.

### Conclusion
Therefore, the number of hydroxy groups attached to boron in borax is **4**.

**Final Answer:** The number of hydroxy groups attached to boron in borax is 4.
