Graphite

Question 1

What are the two types of bonding in graphite

Answer 1

strong covalent

weaker van der Waals forces

Question 2

How many covalent bond does each carbon make in graphite

Answer 2

each forms 3 covalent bonds

Question 3

Graphite is soft slippery substance because

Answer 3

graphite is arranged in layers and sheets of carbon atoms.

The layers in graphite can easily slide over each other because there are weak intermolecular forces holding them together.

Due to its slippery nature, graphite act be used in pencils and as a dry lubricant
.

the flakiness of graphite layers allows iyt to transfer from the pencil to the paper

Question 4

Graphite has a high melting and boiling point.

Answer 4

do to strong covalent bonds between layers

Question 5

Is graphite soluble

Answer 5

Graphite does not dissolve in any solvent. This is because the attraction between the carbon atoms in graphite by covalent bonds is a lot stronger than the attraction that could occur between the solvent molecules and carbon atoms in graphite.

Question 6

Graphite has a low density

Answer 6

because the distance between the layers is large. As the layers in graphite are held together by weak intermolecular forces, the layers are far apart.
