Which one of the following statement is incorrect about the graphite and diamond?
Both the physical and chemical properties of diamond and graphite are different. Graphite is soft, but the diamond is hard. Graphite is a good conductor of electricity while the diamond is not.
Which of the following statement is correct about graphite and diamond?
Due to the presence of delocalised electrons, graphite conducts electricity. Hence, the correct answer to the above question is (c) Graphite and diamond both have giant structures. So, the correct answer is “Option (C) Graphite and diamond both have giant structures.”
Which statement is correct about diamond?
Diamond , an allotrope of carbon, has very high refractive because of which it is used as a grm in jewellery. It is used for cutting glass, marble stones and other hard materials and for drilling of rocks . It is a bad conductor of electricity . It is the hardest material known.
What is common in graphite and diamond?
Both graphite and diamonds are made out of pure carbon. The chemical composition of the two is exactly the same. This makes graphite and diamonds allotropes of carbon along with amorphous, which is commonly called soot or carbon black.
Which one of the following statement is correct for the allotropic forms of carbon?
The correct answer is Diamond is a good conductor of electricity. Allotropes of carbon: Carbon allotropes refer to different well-defined structures of carbon-pure materials, in which the atoms of carbon are bonded in specific ways. Carbon shows allotropic forms like Diamond, graphite, and Buckminsterfullerene.
Is diamond an isomer of graphite?
Definition: Chemical compound that has the same molecular formula – the same number and kinds of atoms – as another compound, but a different structural arrangement of the atoms in space, and, therefore, different properties. For example, graphite (pencil lead) and diamond are isomers of carbon.
Which of the following statements about graphite is not correct?
Graphite has a tetrahedral structure is not correct. Graphite is a naturally-occurring form of crystalline carbon. It is found in metamorphic and igneous rocks.
What is correct graphite?
Graphite, archaically referred to as plumbago, is a crystalline form of the element carbon. Graphite is a naturally occurring form of crystalline carbon. Its atoms are arranged in a hexagonal structure. It is extremely soft, cleaves with very light pressure, and has a very low specific gravity.
Which statement shows that graphite and diamond are different forms of the element carbon?
Both diamond and graphite are made entirely out of carbon, as is the more recently discovered buckminsterfullerene (a discrete soccer-ball-shaped molecule containing carbon 60 atoms). The way the carbon atoms are arranged in space, however, is different for the three materials, making them allotropes of carbon.
How are graphite and diamond similar and different?
Graphite and diamond are two of the most interesting minerals. They are identical chemically – both are composed of carbon (C), but physically, they are very different.
Which characteristic is similar to diamond and graphite?
Diamond and graphite are both allotropes of carbon. This means they are both made up of carbon atoms arranged differently and exist in the same physical state. They both have a giant covalent structure. Diamond has a tetrahedral structure and is the hardest material known to man.
