WebWhat is meta directing deactivators? Deactivators are meta-directing because of the placement of the + charge in the resonance forms of the sigma complex.The meta position becomes more stable because having two + charges next to each other is particularly unstable, as seen in the resonance forms for the ortho and para positions.

WebDeactivating Groups as Meta Directors Electron withdrawing groups like to pull negativity away from the ring. This makes a positive intermediate very unstable, as it desires negativity rather than positivity to stabilize it. As such, electron withdrawing groups slow down, thus deactivating, the EAS reaction. federal estate filing requirements
