`BN` is known as inorganic benzene. True or false

Explanation

To determine whether the statement "BN is known as inorganic benzene" is true or false, we can follow these steps:

### Step 1: Identify the Compound
The compound in question is BN, which stands for boron nitride.

### Step 2: Understand the Structure of Boron Nitride
Boron nitride (BN) can exist in different forms, including hexagonal boron nitride (h-BN) and cubic boron nitride (c-BN). The hexagonal form is particularly relevant for this question.

### Step 3: Compare with Benzene
Benzene (C6H6) is a well-known aromatic compound with a stable ring structure and delocalized π-electrons. In contrast, boron nitride (specifically h-BN) has a similar hexagonal structure to that of benzene but is composed of alternating boron and nitrogen atoms.

### Step 4: Define Inorganic Benzene
Inorganic benzene typically refers to borazine (B3N3H6), which is a compound that has a structure similar to benzene but contains boron and nitrogen atoms. Borazine is often referred to as "inorganic benzene" due to its structural similarity to benzene.

### Step 5: Conclusion
Since BN (boron nitride) is not the same as borazine and is not commonly referred to as "inorganic benzene," the statement "BN is known as inorganic benzene" is **false**. Instead, BN is more accurately described as having a structure similar to graphite.

### Final Answer
**False** - BN is not known as inorganic benzene; it is more accurately described as having a structure similar to graphite.
