Question:
Which one of the following is not correct regarding diamond?
Which one of the following is not correct regarding diamond?
Show Hint
When studying materials, remember that diamond is a form of carbon with exceptional hardness, and its properties differ significantly from other allotropes of carbon like graphite.

- It has a crystalline lattice
- Non-directional covalent bonds are present throughout the lattice
- C-C bond length is 154 pm
- It is used in the manufacture of tungsten filaments
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
- Diamond has a crystalline lattice structure where each carbon atom is tetrahedrally bonded to four other carbon atoms with strong covalent bonds.
- Non-directional covalent bonds do not exist in the diamond structure; instead, every bond is directed and strong.
- The C-C bond length in diamond is approximately 154 pm, which is a characteristic feature of its structure.
- Diamond is not used in the manufacture of tungsten filaments; instead, tungsten is used for this purpose due to its high melting point and conductivity.
