N2 - The effect of surface irregularity on parameters such as surface concentration, area per ligand and interligand distance is discussed with special emphasis on silylation reactions of silica. For the proper evaluation of these parameters, it is suggested that either the effective area for the ligand (and not the nitrogen-BET value) or the fractal (adsorptive or reactive) dimension of the surface be used as a basic parameter, Experimental examples were analysed according to this approach.
