10 sty 2021 · To identify the strongest base we can determine their weakest conjugate acid. The conjugate acids of CH − 3, NH − 2, and S − 2 are CH4, NH3, and HS −, respectively. Next, we consider that acidity increases with positive charge on the molecule, thus ruling out that S − 2 is the weakest base.

Key Concepts and Summary. A Lewis acid is a species that can accept an electron pair, whereas a Lewis base has an electron pair available for donation to a Lewis acid. Complex ions are examples of Lewis acid-base adducts and comprise central metal atoms or ions acting as Lewis acids bonded to molecules or ions called ligands that act as Lewis ...
