Addition to Symmetrical Alkenes
Covers addition to symmetrical alkenes like ethene and cyclohexene. A symmetrical alkene has the same groups attached to both ends of the carbon-carbon double bond.
An explanation of the terms addition and electrophile, together with a general mechanism for these reactions.
The mechanism for the reaction between ethene (and cyclohexene) and hydrogen halides (like hydrogen bromide).
Walkthrough of the mechanism.
The mechanism for the reaction between ethene (and cyclohexene) and sulfuric acid.
Walkthrough of the mechanism.
The mechanism for the reaction between ethene (and cyclohexene) and bromine.

Questions on electrophilic addition to symmetrical alkenes AnswersAddition to Unsymmetrical Alkenes
Covers addition to unsymmetrical alkenes like propene. An unsymmetrical alkene has different groups attached to each end of the carbon-carbon double bond.
