In the diamond form of carbon, there is a network of single, tetrahedrally arragned covalent bonds. The structure of graphite is quite different from that of diamond. Graphitie is composed of many two-dimensional sheets of carbon atoms. The distance between the layers is______pm.

A

`214`

B

`335`

C

`405`

D

`186`

Text Solution

Verified by Experts

The correct Answer is:
B
The distance between the carbon layers is very large `(335 p m)` and is more than twice the value of the van der Waals radius of a `C` atom. Hence, the attraction between layers is very weak.
