PPT-Types of groups and reactions

By MSC Hussien Ali Karim Electron donating group An electron donating group EDG has the net effect of increasing electron density in a molecule through the carbon atom it is bonded to By increasing electron density on adjacent carbon atoms EDGs change the reactivity of a molecule.
