Which of the following is true for diamond?
Diamond is a good conductor of electricity.
Which of the following option is correct regarding diamond structure?
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.
Which of the following is true for diamond diamond is a good conductor of electricity?
Now as we know electrical conductivity relies on the flow of free electrons as there are no free electrons in the diamond so diamond is a bad conductor of electricity. So diamond is a bad conductor of electricity.
Which of the following statements is true for diamond and graphite?
8. Which of the following statements about graphite and diamond is true? Explanation: Both Graphite and diamond being the allotropes of the same element , carbon, have similar chemical properties. So they undergo the same chemical reactions.
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.
What is diamond chemically?
Diamond is an allotrope of carbon and it is present in pure form since it contains carbon atoms bonded to each other.
Which statement about diamond and graphite is not correct answer?
Graphite is a good conductor of electricity while diamond is not.
Which of the following statements about diamond and graphite is incorrect?
Which one of the following statements 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 a good conductor of electricity while the diamond is not.
Which is not a property of diamond?
Diamond is not oxidised by K2Cr2O7/H2SO4 at 200∘C.
Why diamond is a bad conductor of heat?
Metals are good conductors of heat and electricity because they have freely flowing electrons, which carry heat and charge. Insulators don’t have freely flowing electrons, so are usually bad conductors of heat and electricity. Diamond has no freely flowing electrons, so it is a bad conductor of electricity.
Which one of the following is good conductor of electricity?
Now, from the given options graphite is the good conductor of electricity.
Is diamond made up of Cho?
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form of carbon, but diamond almost never converts to it.
|Formula mass||12.01 g/mol|
What is not true about diamond and graphite?
In diamond, each carbon atom forms 4 covalent bonds in a tetrahedral structure. In graphite, the carbon atoms only form 3 covalent bonds, creating hexagonally packed carbon sheets. Graphite is soft, grey, and can conduct electricity reasonably well.
Are diamond and graphite allotropes?
Diamond, graphite and fullerenes (substances that include nanotubes and ‘buckyballs’ , such as buckminsterfullerene) are three allotropes of pure carbon.
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.
