Vedclass · Answer

(C) Graphite is a soft solid lubricant that is extremely difficult to melt. This is because graphite has a layered structure where carbon atoms are arranged in large hexagonal plates (rings) held together by strong covalent bonds within the layers,while the layers themselves are held together by weak van der Waals forces (interplate bonds). These weak interplate bonds allow the layers to slide over each other,making it a lubricant,while the strong covalent bonds within the layers require very high temperatures to break,making it difficult to melt.
