Question:
The bonding present between the carbon atoms of graphite:
The bonding present between the carbon atoms of graphite:
Updated On: Aug 1, 2022
- metallic
- ionic
- covalent
- van der Waals? forces
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In graphite, each carbon atom is $sp^{2}$ hybridised and is linked to three other carbon atoms directly in the same plane by covalent bond ($\sigma$ bond) to form hexagonal ring. These rings constitute huge sheets. The different sheets are joined to each other by weak van der Waals' forces.

Allotropes of Carbon
The existence of a chemical element in one or more physical forms happening in the same physical state is called Allotropes or allotropy. Allotropes may show different physical or chemical states turning on the atom arrangement or the number of existent atoms. While carbon and sulfur is the common element presenting allotropy. Carbon can make further allotropes due to its five-membered valency.
