Key terms
Delocalization
The distribution of electrons across multiple atoms in a molecule, rather than being localized between two atoms.
Electrophile
A species that accepts an electron pair from a nucleophile in a chemical reaction, often seeking to bond with electron-rich areas.
Aromaticity
Aromaticity refers to the increased stability of cyclic compounds with delocalized π-electrons, following Huckel's rule (4n + 2 π electrons).
Electrophile
An electrophile is a species that accepts an electron pair from a nucleophile, often involved in electrophilic substitution reactions.
Electrophile
An electrophile is a species that accepts an electron pair to form a new bond during a chemical reaction.
Aromaticity
Aromaticity refers to the increased stability of cyclic compounds with conjugated pi electron systems that follow Huckel's rule.
Electrophilic substitution
A reaction where an electrophile replaces a hydrogen atom in an aromatic compound.
Nitration
The introduction of a nitro group (-NO2) into an organic compound, typically involving benzene.
