Which is not correct regarding graphite and diamond?

Which of the following statement is not correct regarding diamond and graphite?

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 statement is correct about diamond and graphite?

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 one of the following is not correct about graphite?

Graphite has a tetrahedral structure that is NOT correct about graphite.

What is different about graphite and diamond?

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. … Graphite is very soft and has a hardness of 1 to 2 on this scale. Diamonds are the hardest known natural substance and have a hardness of 10.

Which of the following is not a use of diamond?

Three dimensional network, structure of carbon atoms is formed. C) It is used as an abrasive for sharpening hard tools. D) it can be used as a lubricant.

Which one of the following is not true for diamond?

List – l List – ll

Which of the following statements about graphite and diamond is true they have the same crystal structure?

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.

Can diamond and graphite be used as electrode?

Diamond and graphite can both be used as electrodes. Graphite is also used as a lubricant.

Which is not a property of diamond?

Diamond is not oxidised by K2Cr2O7/H2SO4 at 200∘C.

Do graphite and diamond have the same density?

The differing properties of carbon and diamond arise from their distinct crystal structures. In a diamond, the carbon atoms are arranged tetrahedrally. … This accounts for diamond’s hardness, extraordinary strength and durability and gives diamond a higher density than graphite (3.514 grams per cubic centimeter).

Which of the following statement is true for graphene?

The correct answer is It is a carbon-based nanostructure.

Is graphite a good conductor of electricity?

In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity.

What are 3 differences between diamond and graphite?

For example, Graphite and diamond are two different allotropes of carbon.

Explain the difference in properties of diamond and graphite on the basis of their structures.

1) It has a crystalline structure. 1) It has a layered structure.
2) It is made up of tetrahedral units. 2) It has a planar geometry.

Why is diamond hard and graphite is not?

Diamond is harder than graphite because each of its carbon atoms form four covalent bonds in a tetrahedral structure and also due to the presence of strong covalent bonds in it. A chemical bond involving the exchange of electron pairs between atoms is known as a covalent bond.

What are structures of diamond and graphite?

In diamonds, one carbon atom is bonded with four others to create a dense, cage-like crystal structure that is very hard. In graphite, one carbon bonds with three others to form flat layers that stack like a deck of cards and can slide apart (as seen by the trail of pencil lead).
