9 Diamonds Unveiled: Exploring Allotropy and the Structure of Diamond

The video discusses the allotropic forms of carbon, focusing on diamond. It explains the SP3 hybridization in diamond, its rigid 3D network, and its properties such as hardness, high melting point, and poor conductivity. Diamond's insolubility and chemical inertness are highlighted, along with its uses in jewelry and cutting tools.
