Gilbert Newton Lewis Acids and Bases. The Lewis theory ofacids and basesis the least restrictive model. It does not deal with protons at all but deals with the electron pairs. acids are electron-pair acceptors. bases are electron-pair donors. least restrictive of the acid-base definitions Prop...
Define an acid and a base according to the Bronsted-Lowry concept. Give an acid-base equation and identify each species as an acid or a base. Find the acid or base for N_3^-. What is the role of an acid-base indicator? Define an acid and a base according to the Lewis concept. G...
and the leftover ions combine to produce a salt. If all the available ions combine in this way, the solution becomes pH-neutral, which means that the acid and base neutralize each other. The best-known example is dissolving
chemical reaction, we have a new definition of acidity and basicity, called "Lewis acidity/basicity." ALewis baseis a compound that donates an electron pair to another compound (the ammonia in our example). ALewis acidis a compound that accepts an electron pair (the H+ion in our example)...

What is the definition of a Lewis acid? What is common to all acids? Is sodium bicarbonate a strong or weak base? What are the physical properties of stearic acid? What role do conjugate acid-base pairs play ? The substance (CH3CH2)2NH is considered: a. a neutral compound b. a weak...
A Lewis acid accepts a pair of electrons. A Lewis base donates a pair of electrons. It may seem unnecessary to have two definitions, but it is actually quite useful. For example, the residues histidine, lysine, and arginine are Lewis bases. This is because they can all donate a lone pai...

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...
