Understanding Diamond and Graphite Properties
Both diamond and graphite are allotropes of carbon, but they exhibit significantly different physical properties due to their unique structures.
1. Hardness
- Diamond: It is renowned for its exceptional hardness, making it the hardest naturally occurring material. This hardness is due to its tetrahedral lattice structure where each carbon atom is covalently bonded to four other carbon atoms.
- Graphite: In contrast, graphite is soft and slippery. It consists of layers of carbon atoms arranged in a hexagonal lattice, where weak van der Waals forces allow the layers to slide over each other easily.
2. Electrical Conductivity
- Diamond: It is a poor conductor of electricity. The absence of free electrons in its structure means it cannot conduct electricity effectively, which is typical for insulators.
- Graphite: On the other hand, graphite is a good electrical conductor due to the presence of delocalized electrons in its layers. These electrons can move freely, allowing graphite to conduct electricity.
Evaluation of Statements
- Statement 1: "Diamond is hard and graphite is soft." - This is correct.
- Statement 2: "Diamond is soft and graphite is hard." - This is incorrect.
- Statement 3: "Diamond is a bad conductor but graphite is a good conductor." - This is also correct.
- Statement 4: "Diamond is a good conductor but graphite is a bad conductor." - This is incorrect.
Conclusion
Based on the analysis, the correct statements are 1 and 3. Therefore, the answer is option 'A'.
