Which one of the following statements about allotropes of carbon is incorrect?
- A Graphite is an electrical conductor but the conductivity is direction dependent.
- B Diamond is more dense than graphite.
- C Diamond is metastable.
- D Graphite is thermodynamically less stable allotrope of carbon.
Answer & Solution
Correct Answer
(D) Graphite is thermodynamically less stable allotrope of carbon.
Step-by-step Solution
Detailed explanation
(a) Graphite is an electrical conductor, but the conductivity is direction dependent. (b) Diamond is more dense than graphite is also correct because of layer structure of graphite. (c) Diamond is meta stable is also correct. It is said to be meta stable, because it is…
