Explain diamond. |
|
Answer» SOLUTION :It has a crystalline lattice. In diamond each carbon atom undergoes `sp^3` HYBRIDISATION and linked to four other carbon ATOMS by using hybridised orbitals in tetrahedral fashion. The C-C bond length is 154 pm. The structure EXTENDS in space and produces a rigid three dimensional network of carbon atoms. In this structure directional covalent BONDS are present throughout the lattice. It is very difficult to break extended covalent bonding and therefore, diamond is a hardest substance on the earth. Uses: It is used as an abrasive for sharpening hard tools, in making dyes and in the manufacture of tungsten filaments for electric light bulbs.
