Question

Given below are two statements:
Statement I: Graphite is a good conductor of electricity.
Statement II: Diamond is highly transparent and the hardest known material.
In the light of the above statements, choose the correct answer from the options given below:

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is true but Statement II is false
• D. Statement I is false but Statement Il is true

Answer 1

The Correct Option is A

Let's evaluate the given statements one by one to determine their correctness:

• Statement I: Graphite is a good conductor of electricity.
  • Explanation: Graphite consists of carbon atoms bonded together with strong covalent bonds arranged in layers called graphene. Each carbon atom is bonded to three other carbon atoms, leaving one electron free. These free electrons are delocalized over the layers of graphite, allowing them to move freely and conduct electricity. This ability to conduct electricity makes graphite a good conductor.
• Statement II: Diamond is highly transparent and the hardest known material.
  • Explanation: Diamond is another form of carbon in which each carbon atom is covalently bonded to four other carbon atoms in a 3D tetrahedral structure. This results in an extremely strong lattice, making diamond the hardest known natural material. Additionally, diamond is highly transparent, allowing light to pass through it with minimal absorption.

After evaluating both statements, we determine:

• Both Statement I and Statement II are true. This option is correct as per the explanations provided.

Conclusion: Based on the scientific properties of graphite and diamond, both statements are true. Therefore, the correct answer is: Both Statement I and Statement II are true.
