Explain the difference in properties of diamond and graphite on the basis of their structures.
Options
- ADiamond is a three-dimensional network of covalently bonded carbon atoms, resulting in a hard and transparent
- BDiamond is a layered structure with strong covalent bonds within the layers, making it hard and brittle. Graph
- CDiamond is a layered structure with weak van der Waals forces between the layers, making it soft and slippery.
- DDiamond and graphite have similar structures, but diamond has a higher density due to stronger intermolecular
Correct answer
A. Diamond is a three-dimensional network of covalently bonded carbon atoms, resulting in a hard and transparent
Step-by-step solution
Correct Option is : (A) Diamond is a three-dimensional network of covalently bonded carbon atoms, resulting in a hard and transparent crystalline structure. Graphite, on the other hand, consists of layers of carbon atoms arranged in a hexagonal lattice, held together by weak van der Waals forces, which allows for easy sliding between layers.
