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.
Week 8 Worksheet: Chapter 10 Acids and Bases I. Identifying acid/base theories. For each molecule or ion in the table, identify whether it can act as an acid or a base and put a checkmark under each theory or theories that describe it. Molecule/Ion Acid or Base Arrhenius Bronsted-Lowry Lewis Br-base x CN-base x H2CO3 acid x x NH3 base x HNO2 ...
DEFINITIONS. Lewis acids and bases are defined in terms of electron pair transfers. A Lewis base is an electron pair donor, and a Lewis acid is an electron pair acceptor. An organic transformation (the creation of products from reactants) essentially results from a process of breaking bonds and forming new ones.
