Radical substitution a level chemistry
WebThis is where the substitution takes place, in two steps, and is a chain reaction. In propagation you will make the halogenoalkane and also regenerate the Cl radical. Step 1 The first step involves removing a hydrogen from CH 4 to generate a new radical (the CH 3 radical): Step 2 The second step generates the halogenoalkane and regenerates the ... WebFree radical substitution - Covers free radicals, initiation, propagation, termination, and the curly arrow mechanism. Electrophilic addition - Covers the electrophilic addition mechanism between symmetrical reactants (ethene and Br2), and asymmetrical reactants (propene and HBr), including cation stability and Markovnikov's rule.

WebFree radicals are used up and created in a chain reaction. 1) The free halogen radical attacks a hydrocarbon molecule e.g. Cl• + CH₄ = •CH₃ + HCl 2) This new methyl free-radical (•CH₃) attacks another halogen (Cl₂) molecule. e.g. •CH₃ + Cl₂ = CH₃Cl + Cl• 3) This new free halogen radical can attack another hydrocarbon molecule (loops back to step 1), until all the ...
