What Is Electrophilic Addition Reaction With Example

10 Jun, 2021

Electrophilic aromatic substitution is an organic reaction in which an atom that is attached to an aromatic system usually hydrogen is replaced by an electrophileSome of the most important electrophilic aromatic substitutions are aromatic nitration aromatic halogenation aromatic sulfonation and alkylation and acylation FriedelCrafts reaction. For example ethene bromine 12-dibromoethane.

What is electrophilic addition reaction with example. This takes the form of 3 main steps shown below. These occur between alkenes and electrophiles often halogens as in halogen addition reactionsCommon reactions include use of bromine water to titrate against a sample to deduce the number of double bonds present. Organic chemistry Addition of halogens.

In the last example 12-diodoethene does not suffer further addition inasmuch as vicinal-diiodoalkanes are relatively unstable. As a rule electrophilic addition reactions to alkenes and alkynes proceed by initial formation of a pi-complex in which the electrophile accepts electrons from and becomes weakly bonded to the multiple bond.
