Aromatic Compounds

Aromatic Compounds Historically, benzene and its first derivatives had pleasant aromas, and were called aromatic compounds. Structure of Benzene Kekulé Structure Kekulé (1866) bravely proposed that benzene had a cyclic structure with three alternating C=C double and three C-C single bonds.

Benzene and Aromatic Compounds

2 • Benzene does react with bromine, but only in the presence of FeBr 3 (a Lewis acid), and the reaction is a substitution, not an addition. • Proposed structures of benzene must account for its high degree of unsaturation and its lack of reactivity towards electrophilic addition.

Reactions of Aromatic Compounds

Reactions of Aromatic Compounds Just like an alkene, benzene has clouds of π electrons above and below its sigma bond framework. Diagram 17-1 Although the π electrons are in a stable aromatic system, they are still available for reaction with strong electrophiles.

Aromatic Compounds

Aromatic Compounds Very early in organic chemistry (late 18th, early 19th century) chemists discovered a set of compounds which were unusually stable A number of these compounds had distinct odors Hence they were called 'aromatic' compounds Today the term aromatic is used regardless of the odor ...

AROMATIC COMPOUNDS

AROMATIC COMPOUNDS. A STUDENT SHOULD BE ABLE TO: 1. Name benzene derivatives given the structures, and draw the structures given the names. This includes:

Electrophillic Aromatic Substituion

Reminder: These notes are meant to supplement, not replace, the textbook and lab manual. Electrophilic Aromatic Substitution notes History and Application: Electrophilic Aromatic Substitution (EAS) reactions are a very commonly employed method of making substituted aromatic molecules.

Chemistry of Benzene: Electrophilic Aromatic Substitution

Chemistry of Benzene: Electrophilic Aromatic Substitution • Benzene is aromatic: a cyclic conjugated compound with 6 π electrons • Reactions of benzene lead to the retention of the aromatic core • Electrophilic aromatic substitution replaces a proton on benzene with another electrophile ...

Electrophilic Aromatic Substitution

1 Electrophilic Aromatic Substitution Electrophilic Aromatic Substitution: a reaction in which the hydrogen atom of an aromatic ring is replaced as a result of an electrophilic attack on the aromatic ring Here are three general steps to an electrophilic aromatic substitution: 1.
