Vedclass · Answer

(C) Lewis bases are species that can donate a lone pair of electrons (electron-rich species). In the given list,the Lewis bases are: $NH_3$ (has a lone pair on $N$),$OH^{-}$ (has lone pairs on $O$),$H^{-}$ (has a lone pair),and $Cl^{-}$ (has lone pairs). Thus,there are $4$ Lewis bases. Lewis acids are electron-deficient species: $AlCl_3, H^{+}, Co^{3+}, Mg^{2+}, BF_3$.

Observe the following species: $AlCl_3, NH_3, H^{+}, Co^{3+}, OH^{-}, H^{-}, Mg^{2+}, BF_3, Cl^{-}$. How many Lewis bases are present in the above list?
