WebThe Lewis definition encompasses compounds that the Bronsted-Lowry definition says are acids or bases, and also encompasses compounds that do not donate protons, but still exhibit acid/base behavior. Lewis acids … WebMay 23, 2024 · According to this concept, acids are species (charged or uncharged) that can accept an electron pair or electron-pair acceptors are Lewis acids. Similarly, bases are defined as species that can donate an electron pair, or electron-pair donors are Lewis bases. According to this concept, water is also an example of a Lewis base.
WebThe Lewis Acid definition is a broader one, so encompasses more compounds. A subset of these compounds would also qualify as Bronsted-Lowry Acids, since this definition is much more restrictive. There is no true definition of an acid; a chemical doesn't know if it is an acid or a base or neither. Web< Question 1 of 16 > Which of the choices is the Lewis definition of acids and bases?
