Question

Diamond is covalent yet it has high melting point why?​

Answer 1

Answer:

Each carbon atom is covalently bonded to four other carbon atoms in diamond. A lot of energy is needed to separate the atoms. This is because covalent bonds are strong. This is the reason why diamond has a high melting point.

Answer 2

• Diamond has a 3-dimensional network involving strong C-C bonds
• These C-C bonds are very difficult to break and in turn has high melting point.
