Is diamond most reactive?
Diamond.
Which graphite is more reactive?
Q6) With reference to the structure of the two crystalline allotropes of carbon, state why diamond is inert or unreactive while graphite is comparably more reactive. Solution: The structure of diamond is compact and hence it is unreactive. Graphite has an open structure which makes it more prone to chemical attack.
Which is stronger diamond or graphite?
We know that both diamond and graphite are made of carbon. However, diamond is harder than graphite because of the carbon atoms in a diamond form 4 covalent bonds in the form of tetrahedral structure. This is the reason why diamond is harder than graphite.
What is the reactivity of diamond?
At room temperature, diamonds do not react with any chemical reagents including strong acids and bases. In an atmosphere of pure oxygen, diamond has an ignition point that ranges from 690 °C (1,274 °F) to 840 °C (1,540 °F); smaller crystals tend to burn more easily.
Is diamond more reactive than graphite?
Density: Graphite’s specific gravity is 2.3, which makes it lighter than diamond. Chemical activity: it is slightly more reactive than diamond. This is because the reactants are able to penetrate between the hexagonal layers of carbon atoms in graphite.
Why are diamonds not reactive?
It does not conduct electricity. Every atom in a diamond is bonded to its neighbours by four strong covalent bonds, leaving no free electrons and no ions .
Which is the most reactive allotrope of phosphorus?
White phosphorus is most reactive of all the allotropes of phosphorus because it is unstable due to the angular strain on P4 molecule with the bond angle of 60°.
Why is graphite more reactive than diamond?
Graphite is the most stable allotrope of carbon. Density: Graphite’s specific gravity is 2.3, which makes it lighter than diamond. Chemical activity: it is slightly more reactive than diamond. This is because the reactants are able to penetrate between the hexagonal layers of carbon atoms in graphite.
Why is graphite better than diamond?
Graphite also has a lower density (2.266 grams per cubic centimeter) than diamond. The planar structure of graphite allows electrons to move easily within the planes. This permits graphite to conduct electricity and heat as well as absorb light and, unlike diamond, appear black in color.
Do diamonds turn into graphite?
Diamond is the high-pressure phase that forms deep in the earth. Under normal conditions, diamond is metastable, meaning that it converts back to graphite when the process is initiated with sufficient energy. It can switch its internal structure to a different order, thereby turning into graphite.
Is graphite a compound?
However, graphite is an element and not a compound, and graphite is typically considered a mineral (by definition a mineral cannot be organic), so an argument can be made for its inorganic nature. This compound-forming ability is the result of the structural flexibility of the carbon bond.
What are the difference 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.
