Elemental silicon does not form a graphtie like structure. Explain.

Text Solution

Verified by Experts

The size of silicon atom is more than that of carbon. Therefore `p pi-p pi` bonding is not so effective in case of silicon atom. However, this is present in carbon atoms in graphtie because of smaller size. Thus, silicon cannot have graphtie like structure. Rather, it resembles diamond and is very hard as well as poor conductor of electricity.
