abstract={In chemistry literature it is so far achieved to distinguish <i>o,p</i>-directing groups from <i>m</i>-directing groups purely on the basis of only relative yields of <i>ortho, para</i> and <i>meta</i> electrophilic substituted products in the benzene ring and it is also based on their ability to disturb the pi-electron density at the carbons. It is for the first time in chemistry literature using dipole moment data a linear free energy relationship (LFER), Hammett equation is used to distinguish <i>o,p</i>-directing groups from <i>m</i>-directing groups. This could be achieved by constructing Hammett plots with dipole moments versus Hammett &#963;<SUB>para</SUB> substituent constants for electron donating groups and Hammett &#963;<SUB>meta</SUB> substituent constants for electron withdrawing groups. Good straight lines are obtained with correlation coefficients close to 0.9 with certainly an unmistakable trend.},
