The reactivity of radicals is primarily determined by their electron-deficient nature, making them highly reactive and capable of initiating chain reactions. Their stability is influenced by factors such as resonance, hyperconjugation, and steric effects, which can either stabilize or destabilize the radical species.

Reactivity Of Radicals

Electron-deficient nature

A chain reaction is a sequence of reactions where a reactive product or by-product causes additional reactions to take place. This self-propagating process can lead to exponential growth in the number of reactions, commonly observed in nuclear fission and chemical processes.

Stability factors

Resonance is a phenomenon in which a system oscillates with greater amplitude at specific frequencies, known as its natural frequencies, when subjected to an external force. This effect occurs when the frequency of the external force matches one of the system's natural frequencies, leading to a significant increase in energy transfer and amplitude of oscillation.

Resonance

Hyperconjugation is a stabilizing interaction that results from the delocalization of electrons in sigma bonds (usually C-H or C-C) with an adjacent empty or partially filled p-orbital or a pi-orbital. This phenomenon explains the stability of carbocations and alkenes, contributing to the understanding of molecular structure and reactivity.

Hyperconjugation

Steric effects arise from the physical presence of atoms or groups within a molecule, influencing the molecule's reactivity and properties by hindering or facilitating interactions. These effects are crucial in determining the shape, stability, and reactivity of molecules, impacting fields such as organic synthesis, catalysis, and drug design.
