Graphite has planar hexagonal layers of carbon atoms held together by weak Vander Waals forces and C is s p 2 hybridised. Graphite on the other hand is formed in layers and each carbon is bonded to 3 other carbon atoms. Diamond: each carbon atom bonds to 4 other carbon atoms, WHILST, Graphite: each carbon atom bonds to 3 other carbon atoms. These electrons are free to move between the layers in graphite, so graphite can conduct. Pure diamond is colourless and transparent. 1. 2. Diamond is hard due to its giant covalent lattice and it … It bums in air at 900°C to form carbon dioxide. Electrons are delocalised over the whole sheet. The reason is each carbon atom has one unused electron in p-orbital which overlaps laterally with p-orbital of other carbon atoms to form delocalized pi bonding. In diamond C atom is s p 3 hybridised due to tetrahedral structure. Thus, diamond bears more of a tetrahedral structure, whereas graphite takes the form of layers. Graphite is soft because it has weak inter molecular forces between its layers. Graphites are formed due to the weak van der Waals force of attraction. It is the hardest naturally occurring substance. carbon. It has high density i.e. Diamond and graphite are two allotropic forms of carbon and their crystal structure is different from each other as shown in figure. Diamond is a poor conductor of electricity but is also a good conductor of heat. Diamond is the hardest natural substance and it does not conducts electricity. The electron become free electron. Diamond is the hardest substance known in nature. 3. Graphite, on the other hand, is a good conductor of heat and electricity. and graphite. The distance between the two layers in graphite is 3.4 Å. These both are studied in Organic Chemistry … Diamond and graphite. In diamond, one single atom is connected with other three atoms. Differences 1. They all are different allotropes of Carbon. 3.5 g/cm 3; It is bad conduct of electricity. Diamond. Differences between Diamond and Graphite. are different forms of the element. Graphite is greyish black opaque and shiny. The distance between two layers is longer (3.347 x 10-10 meter) than the distance between carbon atoms within each layer (1.418 x 10-10 meter). Diamond. Graphite and Diamonds are studied in Chemistry. Diamond: Graphite: In diamond, strong three-dimensional networks are formed due to the presence of covalent bonds. Graphite is black and opaque. Why is graphite soft and diamond is hard? Hence, graphite is a weak conductor of electricity. Graphite is a lattice structure. Differences between Graphite and Diamond Chemistry is a subdivision of science in which matters are studied. Difference between diamond and graphite. Graphite. electricity. Diamond is transparent. What is the difference between diamond and graphite structure? The graphite is a good conductor of heat and electricity. It is soft and greasy to touch. The difference in properties of diamond and graphite on the basis of their structures is listed below. These points show the difference between graphite and diamond.
