How do aromatic compounds undergo bromination
WebA: Aromatic compounds or arenes undergo substitution reactions, in which the aromatic hydrogen is… question_answer Q: Describe bromination of aromatic compounds. WebAromatic compounds react mainly by electrophilic aromatic substitution, in which one or more ring hydrogens are replaced by various electrophiles. Typical reactions are chlorination, bromination, nitration, sulfonation, alkylation, and acylation (the last two are Friedel–Crafts reactions). The mechanism involves two steps: addition of the ...
