At such concentrations the reaction has been shown to be of second order (first order with respect to each of OH- and acetophenone). The final product, p-[1-benzoyl-1'-(2,4-dinitrophenyl) methane] has been isolated and characterised. In the reaction medium it forms a purple coloured 1 : 1 molecular complex with m-DNB and it is the variation of absorbance of this complex with time which has been followed spectrophotometrically during the course of the reaction.
