Question

Which of the following models best describes the bonding within a layer of the graphite structure?

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

Answer 1

The correct option is B non-metallic covalent bonding

Structure of graphite

Graphite is a big covalent structure with each carbon atom joined with three other carbon atoms via covalent bonds. Each carbon atom is $s{p}^2$ hybridised. These carbon atoms form a layer like structure with a hexagonal arrangement of carbon atoms.

These layers have weak Van der Waals forces between them. Due to these weak forces, the layers can slip over each other very easily.



Each carbon atom has one non-bonded electron, which gets delocalised.

Thus, non-metallic covalent bonding model best describes the bonding within a layer of the graphite structure.

So, option (c) is the correct answer.
