Lab 6 electrophilic aromatic substitution
Electrophilic aromatic substitution reactions such as nitration, sulfonation, and halogenation are used to add a functional group to the aromatic ring (-no2, -so3h, and -cl or -br, respectively) which may later be converted into a different functional group or serve as a group to direct a. Lab documentation, p6 instructor's notes for a green, guided-inquiry based electrophilic aromatic substitution for the organic chemistry laboratory students can do this experiment in pairs or individually. Summary the structure and properties of aromatic systems were discussed in chapter 11now it is time to visit their chemical reactions the arene system contains an electron rich c=c system which react with electrophiles via a substitution pathway (to preserve aromaticity) via what is known as electrophilic aromatic substitution (ears):. Electrophilic aromatic substitution part 1 electrophilic aromatic substitution (eas): electrophilic attack on aromatic ring leads to hydrogen atom replacement.
Electrophilic aromatic substitution – report written by: katie banas reference: experimental organic chemistry - a miniscale and microscale approach, sixth edition, gilbert and martin discussion an electrophilic aromatic substitution is a reaction that occurs when an atom attached to an aromatic structure is replaced with another molecule, specifically known as an electrophile. Electrophilic aromatic substitution reactions, course notes archive, 6 disclaimer: all images are borrowed from: bruice, p organic chemistrypearsons prentice hall, 2004. 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.

An electrophilic aromatic substitution reaction: the nitration of methyl benzoate in your study of aromaticity, you learned that not all aromatic chemical species are derivatives of benzene but many are. Aromatic compounds can undergo electrophilic substitution reactions in these reactions, the aromatic ring acts as a nucleophile (an electron pair donor) and reacts with an electrophilic reagent (an electron pair acceptor) resulting in the replacement of a hydrogen on the aromatic ring with the electrophile.
