Which of the following is called inorganic benzene?

Options

A. Borazine
B. Graphite
C. Boron nitride
D. none of these

Explanation

To solve the question "Which of the following is called inorganic benzene?", we will follow these steps:

### Step 1: Understand the term "inorganic benzene"
- Inorganic benzene refers to a compound that has a structure similar to benzene but contains elements other than carbon and hydrogen.

### Step 2: Identify the options
- We need to look at the options provided in the question. The common candidates for inorganic benzene include borazine, which is often referred to as inorganic benzene.

### Step 3: Analyze borazine
- Borazine has the chemical formula B3N3H6.
- Its structure consists of alternating boron (B) and nitrogen (N) atoms, with hydrogen (H) atoms attached, resembling the structure of benzene (C6H6) which has alternating carbon atoms.

### Step 4: Compare structures
- Draw the structure of borazine (B3N3H6) and compare it with the structure of benzene (C6H6).
- Both structures are cyclic and planar, and they exhibit similar bonding patterns, which is why borazine is referred to as inorganic benzene.

### Step 5: Conclusion
- Based on the analysis, we conclude that the compound referred to as inorganic benzene is borazine.

### Final Answer
- The answer is **A. Borazine**.
