Kontekstualisasi
Organic chemistry touches many aspects of our everyday lives, from our food choices to the fuels we rely on. Grasping how carbon atoms arrange themselves into various molecular structures is essential for innovating new materials, medicines, and sustainable technologies. The concept of orbital hybridization is key to understanding these structures and their unique properties. For instance, the structure of graphene, a groundbreaking and highly conductive material, is directly linked to the sp² hybridization of carbon atoms.
