Question

diamond has a high melting point why​

Answer 1

Answer:

Each carbon atom is bonded to four other carbon atoms. A lot of energy is needed to separate the atoms indiamond. This is because bonds are strong, and diamond contains very many covalent bonds. This makes diamond's melting point and boiling point veryhigh.

Answer 2

Diamond is a giant covalent structure.The covalent bonds are very strong and require a huge amount of thermal energy to break apart. There are also intermolecular forces that keep the diamond structure together. Thus Diamonds have a high melting point.
