Question

1)Deduce the type of crystal structure shown by graphene.

2)Suggest why graphene is an excellent conductor of electricity.
3) Explain, in terms of its structure and bonding, why graphene has a high melting point.

Answer 1

Graphene is a two-dimensional honeycomb lattice crystal structure that is an excellent conductor of electricity due to its unique bonding. It has a high melting point because of its strong covalent bonds and two-dimensional structure.

Step-by-step explanation:

Graphene is a type of crystal structure known as a two-dimensional honeycomb lattice. It consists of a single layer of carbon atoms arranged in a hexagonal pattern.

Graphene is an excellent conductor of electricity because of its unique structure and bonding. The carbon atoms in graphene are sp2 hybridized, which allows for the formation of pi bonds. These delocalized pi electrons are responsible for the high conductivity of graphene.

Graphene has a high melting point due to its strong covalent bonds and its two-dimensional structure. The carbon-carbon bonds in graphene are very strong, and as a result, it takes a large amount of energy to break these bonds and transition from a solid to a liquid state.
