Exploring reactive intermediates, this overview highlights their role in chemical reactions, such as radicals, carbocations, carbanions, and carbenes. These intermediates are key in transforming reactants into products and are central to reaction mechanisms. Their applications range from industrial processes like catalytic cracking to biological functions involving reactive oxygen species (ROS), which are crucial in cellular signaling and immune defense, but must be regulated due to their potential for cellular damage.
