Brønsted-Lowry or Brønsted theory explainsacid-basereactions as an acid releasing the proton and a base accepting the proton. While the acid definition is somewhat the same as that, which was proposed by Arrhenius (hydrogen ion is a proton), the definition of what constitutes a base is m...
In this process, ammonia is the Lewis base and BH3is the Lewis acid. Generally, the Lewis definition of acids and bases is the most useful because it is the most inclusive of the three definitions. For example, the Brnsted-Lowry definition of an acid includes HF but not BH3, which doe...

Non-Proton Lewis Acid-Base Reactions The Lewis electron-based definition of acids and bases is broad and allows the description of reactions in which no proton is present. For example, boron trifluoride (BF3) and ammonia (NH3), react to form ammonia-boron trifluoride, [B(NH3)F3]. Boron tri...
combine in other ways, however, and when they do, the product isn't always a salt. For example, when you add zinc to ammonia, the reaction results in a complex ion. Until the introduction of the Lewis theory of acids and bases, this wouldn't even have been considered an acid/base ...
It is clear from the reaction that HCl donates a proton which act as an acid and forms Cl– ion which has tendency to accept a proton which act as a base. Similarly, in reverse direction, NH4+ ion accepts a proton and acts as a base. Hence, an acid donates a proton and becomes a...
What do acids and bases have in common? What the difference between strong acids and weak acids? What are seven strong acids? What makes up an acid? What are examples of Lewis acids? What are the properties of organic chemistry? What are the physical properties of stearic acid?
Asymmetric organocatalysis is useful to achieve desired enantiomeric and/or diastereomeric forms of compounds, particularly important in pharmaceutical syntheses. Reactions using organocatalysts typically proceed via four distinct mechanisms based on whether the catalyst acts as a Lewis acid, Lewis base, Bro...
