How does graphite satisfy carbon valency?

In graphite, each carbon atom is bonded to three other carbon atoms in the same plane giving a hexagonal array. One of these bonds is a double-bond, and thus the valency of carbon is satisfied.

Why does carbon only form 3 bonds in graphite?

Graphite can conduct electricity because of the delocalised (free) electrons in its structure. This leaves 1 electron to become delocalised. Its structure is the main reason for this property. Each carbon atom in graphite is directly linked to only three carbon atoms through covalent bonds.

Why does graphite have hexagonal layers?

Graphite is composed of layers of carbon atoms that are arranged in 6-membered, hexagonal rings. In this bonding mode the bond angle between adjacent carbon atoms is 120. These “ring arrays” are arranged in large sheets of carbon atoms, and individual sheets are known as graphene layers.

Does graphite have a free valence electrons?

it has free valence electrons.

What kind of bonding does atoms in graphite has?

covalent bonds
each carbon atom is joined to three other carbon atoms by covalent bonds. the carbon atoms form layers with a hexagonal arrangement of atoms.

Is the valency of carbon satisfied in buckminsterfullerene?

One of these bonds is a double-bond, and thus the valency of carbon is satisfied. The first one to be identified was C-60 which has carbon atoms arranged in the shape of a football. Since this looked like the geodesic dome designed by the US architect Buckminster Fuller, the molecule was named fullerene.

Why graphite is a good conductor of electricity?

In a graphite molecule, one valence electron of each carbon atom remains free. Due to the free electrons in its framework, graphite can perform electricity. Therefore, graphite is said to be a good conductor of electricity.

How many carbon atoms does carbon bond to in graphite?

three

Is graphite an allotrope of carbon?

Diamond, graphite and fullerenes (substances that include nanotubes and ‘buckyballs’ , such as buckminsterfullerene) are three allotropes of pure carbon.

Does graphite follow octet rule?

As there is a free electron in the structure it satisfies all the atoms like resonance. Therefore graphite is stable even when its octet is not complete. Similarly metals also exist as atoms with excess electrons which float freely in the structure.

How many electrons does graphite conduct electricity?

Graphite forms layers of a hexagonal arrangement of atoms and each carbon atom form a covalent bond with three other carbon atoms, and therefore each carbon atom has one non-bonded electron which becomes delocalized and responsible for conducting electricity.

How many bonds does carbon form in graphite?

But in fact carbon does form four bonds in graphite (carbon almost always forms four bonds—a central principle of organic chemistry). The trick is that the four bonds are not always equivalent; in graphite the fourth bond is not formed by the sp2 bonding orbitals but rather involves an unhybridized 2p atomic orbital.

What is the difference between graphite and Diamond?

Whereas in graphite each carbon atom is bonded to three carbon atoms leaving behind one free electron to conduct electricity. Graphite is a good conductor whereas diamond is an insulator. The difference in the geometrical structure of graphite and diamond brings out a large difference in the electrical conductivity of both elements.

What is the C-C-C bond angle in graphite?

This geometry is called trigonal planar and the C–C–C bond angle is 120° (see Figure). All well and good, but this does not really explain why the carbons in graphite/graphene are attached to three other carbon atoms, whereas in diamond each carbon is attached to four others.
