Q.4. What are the main chemical properties of graphite? Answer – It has high melting and boiling point because the bonding between 2 carbon Atom in graphite is covalent and we know that covalent bond is the stronger bond.
WebGraphite does not have a melting point; it changes from the solid state directly into the gaseous state. This process is called sublimation. In an inert gas atmosphere, graphite becomes plastically deformable starting at a temperature of 2500 °C. At temperatures above 3750 °C graphite sublimates even without the presence of oxygen.
