1.	Which of the following allotropes of carbon are hard in nature?(a) Charcoal(b) Diamond(c) Graphite(d) FullerenesThis question was addressed to me in an interview.This key question is from p-Block Elements in portion p-Block Elements of Chemistry – Class 11
Answer» RIGHT OPTION is (B) Diamond The explanation is: The crystalline form of allotropic carbon is diamond, it is the hardest and has a three-dimensional polymeric structure in which hybridization of carbon is sp^3. It is covalent solid, MELTING POINT is 3650-degree centigrade and it is also a bad conductor of heat and electricity.
