"Electrophilic aromatic substitution is an organic reaction in which an atom that is attached to an aromatic system (usually hydrogen) is replaced by an electrophile."
Understanding the properties and reactions of aromatic compounds, including electrophilic aromatic substitution reactions.
"Some of the most important electrophilic aromatic substitutions are aromatic nitration, aromatic halogenation, aromatic sulfonation, alkylation and acylation Friedel–Crafts reaction."
"Aromatic nitration involves the substitution of a hydrogen atom on an aromatic ring with a nitro group."
"Aromatic halogenation is the process of replacing a hydrogen atom on an aromatic ring with a halogen atom, such as chlorine or bromine."
"Aromatic sulfonation involves the introduction of a sulfonic acid group (-SO3H) onto an aromatic ring by replacing a hydrogen atom."
"In alkylation, a hydrogen atom on an aromatic ring is replaced by an alkyl group, which is an alkane chain."
"Acylation involves the substitution of a hydrogen atom on an aromatic ring with an acyl group, usually derived from a carboxylic acid."
"The alkylation and acylation reactions in electrophilic aromatic substitution are commonly referred to as Friedel-Crafts reactions."
"The electrophile is the reacting species that attacks the aromatic system and replaces a hydrogen atom."
"An atom attached to the aromatic system, usually a hydrogen atom, is replaced in electrophilic aromatic substitution."
"Aromatic nitration involves the substitution of a hydrogen atom with a nitro group, while aromatic sulfonation replaces a hydrogen atom with a sulfonic acid group."
"Aromatic halogenation and aromatic sulfonation are considered important electrophilic aromatic substitutions due to their ability to introduce functional groups onto aromatic rings."
"The Friedel-Crafts reaction allows for the introduction of alkyl or acyl groups onto aromatic rings through alkylation or acylation, respectively."
"This paragraph only provides information regarding electrophilic aromatic substitution and does not discuss nucleophilic aromatic substitution."
"The selectivity in electrophilic aromatic substitution reactions is determined by both the reactivity of the electrophile and the position of the hydrogen atom being replaced."
"The general concept of electrophilic aromatic substitution applies to any aromatic compound, but the specifics of the reaction may vary depending on the compound and the substituent being introduced."
"Electrophilic aromatic substitution reactions are extensively used in the synthesis of various organic compounds due to their ability to introduce specific functional groups onto aromatic rings."
"In electrophilic aromatic substitution, an electrophile should possess a positive or partially positive charge and be able to accept an electron pair from the aromatic system."
"The paragraph does not mention the use of catalysts, so it is unclear whether electrophilic aromatic substitution reactions require catalysts or not."
"The paragraph does not provide information about the limitations or challenges associated with electrophilic aromatic substitution."
