Electron donating groups are typically divided into three levels of activating ability (The "extreme" category can be seen as "strong".) Electron withdrawing groups are assigned to similar groupings.

Why Activating Groups Are Ortho And Para Directors?

WitrynaCategories. Deactivating groups are generally sorted into three categories.
