SUMMARY

The discussion centers on the behavior of diamond when exposed to temperatures above 750°C in the presence of oxygen. It is established that the covalent C-C bonds in diamond are broken during combustion, leading to the formation of C=O double bonds. This process is classified as oxidation, which involves both breaking existing bonds and forming new ones. The conversation highlights the chemical reactions that occur when diamond burns, confirming that bond breaking is essential for the reaction to take place.

PREREQUISITES
  • Covalent bonding concepts

We all know that when we scratch a diamond with another diamond, millions and millions of covalent bonds are broken. I would like to ask what happens when a diamond burns in the atmosphere at temperatures above 750 C? Does the reaction of oxygen and carbon also break the bonds, or are we dealing with a different phenomenon here?

Yes, explicitly chemical reactions involve the breaking and/or forming of bonds. In the case of diamond, the C-C bonds are broken, and C=O double bonds are formed.
