In graphite, the different layers are held together by

Options

A. ionic bonding
B. covalent bonding
C. van der Waals forces
D. metallic bonding

Explanation

To solve the question "In graphite, the different layers are held together by," we will follow these steps:

### Step 1: Understand the Structure of Graphite
Graphite is an allotrope of carbon. In graphite, each carbon atom is bonded to three other carbon atoms, forming a hexagonal planar structure. This results in a layered arrangement of carbon atoms.

**Hint:** Think about how carbon atoms bond in different forms and what structure they create.

### Step 2: Identify the Type of Bonding Within the Layers
The carbon atoms within each layer are held together by strong covalent bonds. Each carbon atom forms three covalent bonds with three neighboring carbon atoms, creating a stable and strong network within each layer.

**Hint:** Recall the types of bonds and which ones are strong versus weak.

### Step 3: Examine the Interaction Between the Layers
While the carbon atoms within a layer are held together by covalent bonds, the layers themselves are not bonded as strongly. The layers in graphite are held together by weak intermolecular forces known as Van der Waals forces. These forces allow the layers to slide over each other easily, which is why graphite is slippery and can be used as a lubricant.

**Hint:** Consider how layers of materials interact with each other and what types of forces might be at play.

### Step 4: Conclusion
Based on the understanding of the structure of graphite and the types of bonding involved, we conclude that the different layers in graphite are held together by Van der Waals forces.

**Final Answer:** The different layers in graphite are held together by Van der Waals forces.
