Substitution reactions

Learning objectives :

  • understand the mechanism of the free radical substitution reaction between an
    alkane and a halogen:
    (i) using free radicals, which are species with an unpaired electron, represented by
    a single dot
    (ii) showing the initiation step of the mechanism, with curly half-arrows for free
    radical formation
    (iii) showing the propagation and termination steps of the mechanism
    (iv) having limited use in synthesis because of further substitution reactions
