PASSAGE-I : Diamond and graphite are two allotropic forms of carbon which are crystalline in nature. They differ physically but chemically they are similar. Diamond is the hardest crystalline form of carbon. In diamond each carbon atom is linked to four other carbon atoms by covalent bonds. In graphite, each carbon atom is linked to three other carbon atoms by covalent bond. Graphite is relatively soft and greasy. It is a good conductor or electricity. Which allotrope gives carbon dioxide on heating?
