Diamond is one of the 8 allotropes of carbon.
Properties of a diamond:
1. It is the hardest known material.
2. Diamond is non - metallic.
3. It has high thermal conductivity, i.e., it is a good conductor of heat.
4. It has a very low electrical conductivity, i.e., it is a terrible conductor of electricity, or it does not conduct electricity at all, and it is used as an insulator also.

Understanding Diamond Properties
Diamond is a fascinating material known for its unique properties. Let's break down the statements to identify why option 'D' is not true.
1. Hardness
- Diamond is renowned for being the hardest known natural material on the Mohs scale, rated at 10.
- Its exceptional hardness is due to the strong covalent bonding between carbon atoms in a tetrahedral lattice structure.
2. Non-metallic Nature
- Diamond is classified as a non-metal.
- Unlike metals, it does not conduct electricity due to the absence of free electrons.
3. Thermal Conductivity
- Diamond exhibits high thermal conductivity, making it an excellent conductor of heat.
- This property is attributed to its strong covalent bonds and the orderly arrangement of carbon atoms.
4. Electrical Conductivity
- Unlike metals and some other materials, diamond does not conduct electricity effectively.
- This is because diamond lacks free-moving charge carriers (electrons), which are essential for electrical conductivity.
- Therefore, it acts as an insulator rather than a conductor.
Conclusion
In summary, the statement regarding diamond having very high electrical conductivity is incorrect. While diamond exhibits remarkable hardness, high thermal conductivity, and is non-metallic, it does not conduct electricity, making option 'D' the right answer.
