Diamond is extremely hard whereas graphite is soft. This is because
- A diamond is covalent, whereas graphite is ionic
- B diamond is ionic whereas graphite is covalent
- C each carbon atom in diamond is chemically bonded to greater number of neighbouring carbon atoms
- D certain atoms in diamond are smaller in size
Answer & Solution
Correct Answer
(C) each carbon atom in diamond is chemically bonded to greater number of neighbouring carbon atoms
Step-by-step Solution
Detailed explanation
In diamond carbon atom is sp3 hybridised due to tetrahedral structure. In diamond each carbon atom is present at the same distance to each of its neighbouring carbon atom. In this rigid network atom cannot move that is why diamond are so hard. Graphite is layered. Graphite has…
