Organic Chemistry: Electrophilic Addition Mechanism Video

February 22, 2017 By Sean Chua Leave a Comment

Alkenes are unsaturated hydrocarbons with the general formula CnH2n. They contain the carbon-carbon double bond, C=C in their structures and are named with the suffix -ene.

Alkenes are much more reactive than the alkanes because the C=C bond contains delocalized π cloud electrons which can attract electrophiles (positive charged particles) or even induce dipoles, thereby creating electrophiles in some nearby particles. Alkenes typically undergo Electrophilic Addition reactions such as:

  • Addition of H2(g)
  • Addition of H2O(g)
  • Addition of Halogens, X2(g)
  • Addition of Aqueous Halogens, X2(aq)
  • Addition of Hydrogen Halides, HX(g)

It is important that students understand the Electrophilic Addition Mechanism in order to predict the likely products after an alkene undergo Electrophilic Addition Reactions with added reagents.

In the video below, you will learn the 2 Steps involved in Electrophilic Addition Mechanism using ethene, C2H4, a symmetrical alkene reacting with Br2 (dissolved in CCl4).

Many know me as the Ten Year Series book author for JC A-Level H2 Chemistry and O-Level Pure Chemistry. My 19+ years of coaching experience (since 1999) with more than 1500 students from 180+ JCs and Secondary Schools has allowed me to understand the true reasons why students are not able to perform well in Chemistry. Most importantly, my strength lies in using everyday analogies (even grandmothers can understand!) to simplify abstract concepts. Also, my teaching methodology has been designed to be fun, enjoyable and effective for my students.
