WebJul 19, 2024 · In this article, we look at how electron-donating and electron withdrawing substituents direct the substitution on a benzene ring. Electron-donating substituents In the synthesis of disubstituted benzenes, the cation resulting from ortho-para addition with … WebApr 11, 2024 · The higher electronegativity of C/N enables electron gain from Al. By comparison, the Al atom’s capacity of electron donating is weaker than that of Mg atom within the pore of g-C 3 N 4 (1.6 e −); and this explains why the adsorption of Al is relatively weaker . Additionally, we found that in the bound structure, Al was polarized to form a ...
