The correct answer is:
4
Lewis bases (electron rich) $=\mathrm{NH}_3, \mathrm{OH}^{-}, \mathrm{H}^{-}, \mathrm{Cl}^{-}$
Lewis acids (electron deficient) $=\mathrm{AlCl}_3, \mathrm{H}^{+}, \mathrm{Co}^{3+}, \mathrm{Mg}^{2+}$, $\mathrm{BF}_3$
Lewis acids (electron deficient) $=\mathrm{AlCl}_3, \mathrm{H}^{+}, \mathrm{Co}^{3+}, \mathrm{Mg}^{2+}$, $\mathrm{BF}_3$
