A strong base is a basic chemical compound that can remove a proton (H +) from (or deprotonate) a molecule of even a very weak acid (such as water) in an acid–base reaction. Common examples of strong bases include hydroxides of alkali metals and alkaline earth metals, like NaOH and Ca (OH) 2, respectively.
Acids and bases. A Lewis acid (named for the American physical chemist Gilbert N. Lewis) is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct. A Lewis base, then, is any species that has a filled orbital containing an electron pair which is not involved in ...
An organic base is an organic compound which acts as a base. Organic bases are usually, but not always, proton acceptors. They usually contain nitrogen atoms, which can easily be protonated. For example, amines or nitrogen-containing heterocyclic compounds have a lone pair of electrons on the nitrogen atom and can thus act as proton acceptors. [ 1]
The Brønsted–Lowry theory (also called proton theory of acids and bases[ 1]) is an acid–base reaction theory which was first developed by Johannes Nicolaus Brønsted and Thomas Martin Lowry independently in 1923. [ 2][ 3] The basic concept of this theory is that when an acid and a base react with each other, the acid forms its conjugate ...
In organic chemistry, a Schiff base (named after Hugo Schiff) is a compound with the general structure R1R2C=NR3 ( R3 = alkyl or aryl, but not hydrogen ). [ 1][ 2] They can be considered a sub-class of imines, being either secondary ketimines or secondary aldimines depending on their structure. Anil refers to a common subset of Schiff bases ...
an organic acid; is one of the simplest carboxylic acids. Acetone. an organic compound; simplest example of the ketones. Acetylene. a hydrocarbon and the simplest alkyne; widely used as a fuel and chemical building block. Ammonia. inorganic; the precursor to most nitrogen-containing compounds; used to make fertilizer. Ammonium hydroxide.
Buffer solutions resist pH change because of a chemical equilibrium between the weak acid HA and its conjugate base A −: HA ⇌ H + + A − When some strong acid is added to an equilibrium mixture of the weak acid and its conjugate base, hydrogen ions (H + ) are added, and the equilibrium is shifted to the left, in accordance with Le ...
Bases are defined by the Brønsted–Lowry theory as chemical substances that can accept a proton, i.e., a hydrogen ion. In water this is equivalent to a hydronium ion). The Lewis theory instead defines a Base as an electron -pair donor. The Lewis definition is broader — all Brønsted–Lowry bases are also Lewis bases.
