Question

why does graphite has a high melting point

Answer 1

Each carbon atom is bonded to 3 other carbon atoms using very strong covalent bonds. The 4th electron is a delocalised electron, which bonds each layer of carbon to the other layers. This bond is very weak, but that's not really important/relevant to your question. The bonds connecting each layer together are very weak, (intermolecular bonds) and do not require much heat or energy to break apart, but the bonds holding together the layers (intramolecular bonds) are very strong, plus graphite is held in a very strong and sturdy (2D) lattice structure, so it requires a lot of energy, ie. a lot of heat to break apart.

Answer 2

Answer:

Why graphite has a high melting point even having weak force of attraction?

Explanation:

graphite still has a very high melting and boiling point because the strong covalent bonds that hold the carbon atoms together in the layers require a lot of heat energy to break.

hope it helps!
