Question

Select the correct options from the following :

• A. Graphene is an atomic layer of graphite.
• B. Graphene is an atomic layer of composed of $s{p}^2$-hybridised carbon.
• C. Chemical bonds in graphite are similar in strength to that of diamond
• D. All of these

Answer 1

The correct option is D All of these

Graphene is an atomic layer of graphite. Single layer of carbon atoms is arranged in a hexagonal lattice.

Graphene is an allotrope of carbon.

In graphene (and in graphite) C atoms are $s{p}^2$ - hybridised.

Chemical bonds in graphite are similar in strength to that of the diamond. But the diamond is stronger than graphite due to its rigid three-dimensional structure that results in an infinite network of atoms.
