Diamond is covalent yet it has high mp
Web(1)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.(2)In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of … WebIt is the bonding between the carbon atoms in diamond because of which it is hard and has high melting point. In diamond, each carbon atom is bonded to four other carbon by sigma bonds, forming a rigid three dimensional structure, which means very high amount of energy is required to break the bonds and hence results in high melting point.
