a Lewis base, consider which compounds in a reaction have an available electron pair to donate and which compounds need to receive an electron pair. Since the definition of a Lewis base is a species that forms a covalent bond by donating an electron pair, a Lewis acid is a species that ...
Lewis Acid Example An example of an acid/base reaction that can't be described by the Bronsted-Lowry definition is Al3+ in water. Aluminum Hexa-aqua Complex Al3+ is a hard Lewis acid. It reacts with water to produce an aqua complex Al(H2O)63+. In this complex, the Al3+ accep...
Another example: [Ag (NH3) 2]+ = I + 2NH3: AgI Alkali (I) replaces the base complex (NH3) of the acid-base complex [Ag (NH3) 2], forming a new acid-base complex, AgI. 4. double substitution reaction, the acid and base of two acid-base complexes cross each other to replace,...

Lewis Acid/Base Theory A Lewis base is a species with an available (reactive) pair of electrons and a Lewis acid is an electron pair acceptor. The simplest reaction is for a Lewis acid to interact with a Lewis base to give a Lewis acid/base complex:...
withsilver ion(or other cation) as an acid and ammonia (or other electron-pair donor) as a base. In reactions such as this, the product is often called an adduct, a product of the reaction of aLewis acidand base to form a new combination. Another example of a Lewis acid-base adduct...
Theoretical studies for Lewis acid-base interactions and C-H...O weak hydrogen bonding in various CO2 complexes. Comprehension of the basic concepts for the design of CO2-philic molecules is important due to the possibility for "green" chemistry in supercritical CO2 of substitute solvent systems....
The reaction described above indicated that β,γ-unsaturated 2-acyl imidazoles performed both α-addition reaction and β-addition upon isomerization under proper Lewis acid catalysts. Next, to extend the scope of α-addition of β,γ-unsaturated 2-acyl imidazoles, several types of imines3were ex...
