Lab 6 electrophilic aromatic substitution

lab 6 electrophilic aromatic substitution Activation and deactivation and directing effects because the benzene acts as a nucleophile in electrophilic aromatic substitution, substituents that make the benzene more electron-rich can accelerate the reaction.

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.

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.
