In this electrophilic aromatic substitution, the first electrophile is the Lewis acid that accepts the halogen from an alkyl halide. |
|
A nitronium ion, made by treating nitric acid with sulfuric acid, is the electrophile. |
|
In this reaction the electrophile is produced when the methyl chloride reacts with the aluminum chloride to form an electropositive CH 3 group. |
|
This produces the second electrophile, the positively charged alkyl group. |
