    complex reactions and reaction sequences‚ where raw materials react together to give the product. Such chemical process often releases energy‚ in the form of heat‚ and the reaction is described as exothermic. Many of these reactions may also evolve gases at high rates‚ and could cause reactor over-pressure. Thermal runaway reaction Runaway reactions are thermally unstable reactions where the heat of reaction can raise the temperature of the reactants sufficiently to accelerate the reaction rate out

    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
