Which of the following attractive forces exists between different layers of graphite?

Correct option is A

The correct answer is (a) Van der Waals forces.
· In graphite, the carbon atoms within each layer are strongly bonded together by covalent bonds, forming a hexagonal lattice. However, the different layers of graphite are held together by much weaker Van der Waals forces. These forces allow the layers to slide over each other easily, giving graphite its characteristic slippery feel and making it an excellent lubricant and material for pencils.
Information Booster:
· Gravitational forces: These are the weakest of all fundamental forces and are not responsible for the bonding between graphite layers.
· Coulombic forces: These are the electrostatic forces between charged particles, not relevant to the bonding between neutral carbon layers in graphite.
· Electromagnetic forces: A broad term that includes both electric and magnetic forces, but not specifically the weak interlayer forces in graphite.
