Diamond and graphite are allotropes of carbon. These have different chemical and physical properties. The main difference between diamond and graphite is that diamond is made out of sp3 hybridized carbon atoms whereas graphite is made out of sp2 hybridized carbon atoms.
Why is diamond and graphite so 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.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.
What are differences between diamond and graphite?
| Diamond | Graphite |
|---|---|
| It has crystalline nature | It has layered structure |
| Each C is sp3 hybridzed and forms 4 covalent bonds with neighboring C atoms. | Each C atom is sp2 hybridized and forms 3 sigma bonds with 3 other C atoms. Fourth electron forms pi bond. |
| The geometry is tetrahedral. | The geometry is planar |
What are 3 differences between diamond and graphite?
Difference between diamond and graphite.
The p-Block Elements.

|---|---|
| 4. It has huge three dimensional network structure. | 4. It has two dimensional sheet like structure. |
| 5. It does not possess any lustre | 5. It a has metallic lustre. |
| 6. It a has very high melting point. | 6. It has low metling point. |
Why are graphite and diamond not similar?
Graphite and Diamond are different because they have different structures. Both have Giant Covalent Structures, resulting in very high melting temperatures. However each carbon atom in Diamond has 4 covalent bonds with other Carbons, making it extremely strong and hard.
How is graphite similar to 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.
What is the similarity and difference between 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.
What is the difference between graphite and diamond in terms of structure?
Diamond: each carbon atom bonds to 4 other carbon atoms, WHILST, Graphite: each carbon atom bonds to 3 other carbon atoms. Thus, diamond bears more of a tetrahedral structure, whereas graphite takes the form of layers.
How does diamond and graphite differ in terms of electrical conductivity and hardness?
Graphite, for example, has a melting point of more than 3,600°C. Variable electrical conductivity – diamond does not conduct electricity, whereas graphite contains free electrons so it does conduct electricity. Silicon is a semi-conductor – it is midway between non-conductive and conductive.
Why is graphite less dense than diamond?
Graphite has a lower density than diamond. This is because of the relatively large amount of space that is “wasted” between the sheets. Graphite is insoluble in water and organic solvents – for the same reason that diamond is insoluble.
Why do diamond and graphite differ in physical properties?
It’s because the carbon atoms are rearranged in a specific geometric shape that gives the diamond its properties.Graphite however, is when the carbon atoms bond together in sheets – hexagonal-like lattice. Graphite is formed from the carbon atoms resulting from the metamorphism of minerals such as marble, quartz, etc.
What is difference between graphite and diamond class 10?
Answer: The difference in properties of diamond and graphite on the basis of their structures is listed below. In diamond, strong three-dimensional networks are formed due to the presence of covalent bonds. Graphites are formed due to the weak van der Waals force of attraction.
How does the conductivity vary in diamond and graphite?
Since electrical conductivity relies on the flow of free electrons, diamond is not a good conductor. Graphite on the other hand, although also only made up of carbon atoms, is the only non-metal that can conduct electricity.
Why graphite has higher melting point than diamond?
The melting point of graphite is slightly larger than the melting point of diamond, because in graphite C-C bonds have a partial double bond character and hence are stronger and more difficult to break.
Is diamond a good conductor of electricity?
Due to the tetrahedral arrangement of covalently bonded carbon atoms in diamonds, there are no free electrons that can move and carry currents in diamonds. Since the conduction of electricity requires the presence of free electrons. Hence, diamond is a bad conductor of electricity.
Which is harder graphite or diamond?
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.
What is harder than a diamond?
(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.
Are diamond and graphite allotropes?
Diamond, graphite and fullerenes (substances that include nanotubes and ‘buckyballs’ , such as buckminsterfullerene) are three allotropes of pure carbon.
