Elimination Reactions ________________________________________ As described previously‚ primary alkyl halides generally undergo substitution reactions with simple nucleophiles by an SN2 mechanism. Secondary alkyl halides‚ often react with simple basic nucleophiles to give a mixture of products arising from both substitution and elimination. As with substitution reactions‚ the rate at which elimination reactions proceed can be proportional to both the concentration of the base and the concentration
