Theory of Meta directing group The substituent, S takes electrons from para and ortho positions. So, m-position becomes a position of comparatively high electron density and further substitution through electrophile occurs at Meta position. For instance, -NO2 group is a Meta directing (Electron withdrawing). Its procedure can be demonstrated as:  All meta-directing sets comprise either a partial positive charge or a full positive charge on the atom straight attached to the ring.   Posted Date: 4/18/2013 5:20:33 AM | Location : United States
