Reactive Intermediates
Explore CurlyArrows tutorials on reactive intermediates in organic chemistry — carbocations (formation, types, stability via inductive, resonance, hyperconjugation), carbanions (formation, stabilization, acidic proton), and free radicals (structure, types, stability, dissociation energies). Includes the fate of each intermediate and common reactions.

Carbocations and electrophiles are both electron-deficient species and therefore are electron acceptors. They are attracted to electron-rich centers.
Chemistry Glossary
Benzynes, also known as Arynes, are highly reactive intermediates formed in organic chemistry aromatic reactions. It is identified as containing a triple bond between two adjacent carbons of the benzene ring. One crucial difference separates Benzyne from Benzene...
A carbocation is a positively charged, trivalent carbon ion that acts as a reactive intermediate in many organic reactions.
A carbanion is a negatively charged, trivalent carbon ion that acts as a reactive intermediate in many organic reactions.
Electrophiles are electron-deficient species that accept electrons from other electron-rich counterparts, the nucleophiles, to form a two-electron covale
Short Answer Question
Radical initiators are chemical species that quickly produce free radicals by light and heat exposure.
A radical reaction usually happens in three steps- Initiation (creation of free radicals), Propagation (multiplication and growth of radical reaction), and Termination (sto
Free radicals are generated due to the homolytic bond cleavage, a type of bond breaking where each atom holding the two-electron covalent bond gets one electron.
A carbocation is a positively charged, electron-deficient ion of carbon with only 6 valence electrons from the preferred 8 for covalent bonding.
