3.3.4.2 Addition reactions of alkenes

Content	Opportunities for skills development
$Electrophilic addition reactions of alkenes with HBr, H₂SO₄ and Br₂ The use of bromine to test for unsaturation. The formation of major and minor products in addition reactions of unsymmetrical alkenes. Students should be able to: outline the mechanisms for these reactions explain the formation of major and minor products by reference to the relative stabilities of primary, secondary and tertiary carbocation intermediates.$	$AT d and k PS 4.1 Students could test organic compounds for unsaturation using bromine water and record their observations.$
