Which of the following is correct statement for diamond?
Notes: Diamond is the hardest natural substance known on earth. Diamond is extremely hard and transparent. It doesn’t conduct electricity and has a higher melting point than Graphite. At room temperature, diamonds do not react with any chemical reagents including strong acids and bases.
Which of the following statements are true about diamond and graphite?
Answer: D) They can undergo the same chemical reactions. Explanation: Diamond and graphite are both made up of carbon and have same chemical properties as that of carbon and they both undergo same type of chemical reactions.
Which is are true statements diamond is unaffected?
Diamond is unaffected by conc acids but graphite reacts with hot conc. HNO3 forming mellitic acid, C6(COOH)6.
What are the characteristics of diamond?
Actually diamond has four main characteristics such as clarity, cut, carat and color. Each characteristic has an impact on cost and price of diamond thus, it’s important to know what these characteristics are and how they affect the diamond’s price.
What is a diamond an example of?
Hence, diamond is an example of network covalent solid.
What type of element is diamond?
Diamond is composed of the single element carbon, and it is the arrangement of the C atoms in the lattice that give diamond its amazing properties. Compare the structure of diamond and graphite, both composed of just carbon.
Which statement about diamond and graphite is not correct?
Diamond has a tetrahedral structure, whereas graphite has a hexagonal planar structure. 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 one of the following statement about diamond and graphite is not correct?
Graphite is a good conductor of electricity while diamond is not.
Which of the following statements about diamond and graphite is not correct?
The correct option is D. Note: Structure of diamond is crystalline. In diamond each atom present in diamond makes four other covalent bonds with neighboring carbons. Graphite is a layered structure and each layer one carbon atom bonds with 3 other carbon atoms while 1 electron remains free to move between layers.
Who proved that diamond is a form of carbon?
Platinum – Platinum is a chemical element with atomic number 78 and the symbol Pt. It’s a silverish-white transition metal that’s dense, malleable, ductile, and very unreactive. It gets its name from the Spanish word platino, which means “small silver.” Diamond is a form of carbon, as Davy and Faraday demonstrated.
Is diamond a conductor of electricity?
Diamond is a crystalline form of carbon which is good conductor of electricity.
Why is diamond an allotrope of carbon?
Diamond is made of more 3-dimensional molecules. Rather than being in neat layers alone, the layers are bonded together and form an even stronger but not conductive material. It is made only out of carbon, so is an allotrope of carbon.
