The classical concepts of steric inhibition of resonance (SIR) and primary steric effect (van der Waals interactions) were revised with the aid of methyl-substituted benzoic acids. The quantum chemical model was based on the energies of various conformations, calculated at the RHF/6-31 +G(d,p) and B
## Abstract The isomer distributions for the sulfonation of the twelve halogenotoluenes and some trisubstituted halogenomethylbenzenes, with both 98.4% H~2~SO~4~ at 25Β°C and sulfur trioxide in nitromethane at 0Β°C, have been determined and found to be very similar.
