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:. Stoichiometry. Do Now:. True or false:. Most ionic substances need an aqueous medium in order to react.. Reactions occur at the level of atoms and molecules, therefore count of each reactant atoms/molecules/ions needs to be known in order to determine how much product can be produced. . Objective.
