Strong bases effect bimolecular elimination.. At higher concentrations of strong base, the rate of alkene formation becomes proportional to both the starting halide and the base.. Under these conditions the second order kinetics are called bimolecular elimination or E2.. Tiny. . Interpolants. and . Near-interpolants. . from a . Resolution Refutation.
