Which statement about the allotrope diamond is correct?
Answer
It is an excellent thermal conductor
The correct answer is It is an excellent thermal conductor — Select the option that matches the property of high thermal conductivity.
Step-by-step solution
- Recall that diamond consists of a three‑dimensional network of hybridised carbon atoms.
- Such a structure gives diamond a very high thermal conductivity, much greater than that of most substances.
- Check each option: electricity conduction is absent, layered structure belongs to graphite, hybridisation also belongs to graphite.
- Select the option that matches the property of high thermal conductivity.
Common mistake: Confusing diamond’s high thermal conductivity with electrical conductivity or with graphite’s layered structure.
