Diamond has high melting point - Explain.

Text Solution

Verified by Experts

`to` In Diamond each carbon undergoes `sp^(3)` hybridisation and it is surrounded by four other carbon atoms with strong-o-bonds tetrahedrally.
The C-C bond energy in diamond is very high and it has 3-dimensional structure.
`to` Due to these reasonis diamond has high melting point.
`to` It has melting point 4200 K .
