How do aromatic compounds undergo bromination
Did you know?
WebAromatic compounds react by electrophilic aromatic substitution reactions, in which the aromaticity of the ring system is preserved. For example, benzene reacts with bromine to … WebMar 7, 2024 · Aromatic compounds, unlike ordinary alkenes, are less reactive compared to their acyclic counterparts due to their relative stability afforded by π electron delocalization. In a halogenation reaction known as bromination, Br2 can readily react with ethane to produce dibromoethane. This is not true for benzene.

WebWhen substituted benzene compounds undergo electrophilic substitution reactions of the kind discussed above, two related features must be considered: I. The first is the relative reactivity of the compound compared with benzene itself. Experiments have shown that substituents on a benzene ring can influence reactivity in a profound manner. WebStep 1. Initiation. The initiation step involves the homolytic cleavage of a Cl-Cl bond to form two Cl atoms. Step 2. Propagation. A C atom removes an H from methane, producing HCl and a methyl radical. The newly-formed methyl radical abstracts a Cl from a chlorine …
