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.
