Question

Which of the following structure is similar to graphite ?

• A. BN
• B. B
• C. B₄C
• D. B₂H₆

Answer 1

The Correct Option is A

The question asks which structure is similar to that of graphite. To determine the correct answer, let's analyze each option:

1. Graphite Structure:

   Graphite is an allotrope of carbon where each carbon atom is bonded to three other carbon atoms in the same plane, forming a hexagonal structure. These planes are stacked and held together by weak van der Waals forces, allowing them to slide over each other. Graphite has a layered, planar structure.

2. BN (Boron Nitride):

   Boron Nitride (BN) can exist in a structure similar to graphite, known as hexagonal boron nitride (h-BN). In h-BN, boron and nitrogen atoms are arranged in a similar hexagonal pattern as in graphite, with layers that can slide over each other.

3. B (Boron):

   Boron does not form a structure like graphite. It typically forms complex structures but not planar, layered structures like graphite.

4. B₄C (Boron Carbide):

   Boron carbide does not have a graphite-like structure. It has a very different crystalline structure, which is rigid and does not have the layered characteristic of graphite.

5. B₂H₆ (Diborane):

   Diborane is a compound with a unique structure and does not exhibit the layered structure seen in graphite.

Thus, based on the structural similarities, the correct answer is BN (Boron Nitride) because hexagonal boron nitride mimics the layered structure of graphite.
