An Introduction of Lewis Acid and Base
Lewis Acid and Base – Examples: Lewis acid and base are two types of chemical species that can interact with one another. A Lewis acid is a species that can donate an electron pair to a Lewis base. A Lewis base is a species that can accept an electron pair from a Lewis acid.
When a Lewis acid and base interact, they form a Lewis adduct. A Lewis adduct is a species that contains a covalent bond between the Lewis acid and base. The Lewis adduct can be either a covalent or ionic compound.

What is Lewis Acid?
A Lewis acid is an atom or molecule that can accept a pair of electrons from another atom or molecule.
Examples of Lewis Acids
A Lewis acid is an electron-pair acceptor. In other words, it is a molecule that can accept an electron pair from another molecule. This electron pair can then be used to form a new chemical bond.
Some examples of Lewis acids include:
- Sulfuric acid
- Nitric acid
- Phosphoric acid
- Carbonic acid
- Boron trifluoride
- Aluminum chloride
Applications of Lewis Acids and Bases
The Lewis acid and base are two types of chemical species that can be used to manipulate chemical reactions. The Lewis acid is a molecule that can donate a Lewis electron pair to another molecule, while the Lewis base is a molecule that can accept a Lewis electron pair. This electron pair donation and acceptance can be used to initiate or promote chemical reactions.
What is Lewis Base?
Lewis Base is a nitrogenous base found in the DNA of all living cells. It is named after Gilbert N. Lewis, who first proposed its existence in the early 1900s.
Examples of Lewis Bases
- NH 3
- H 2 O
- CH 3 NH 2
Applications of Lewis Bases
Lewis bases used in a variety of applications, including:
- In organic chemistry, Lewis bases often used to donate a pair of electrons to a molecule or atom that is deficient in electrons. This process known as electron-pair donation.
- Lewis bases are also used as ligands in coordination chemistry. In this context, a Lewis base donates a pair of electrons to a metal ion, forming a coordinate covalent bond.
- Lewis bases can also be used to catalyze certain chemical reactions. In particular, Lewis bases are often used to promote the formation of carbon-carbon bonds.
Chemical Reactions between Lewis Acids and Bases
When a Lewis acid and a Lewis base react, the acid donates an electron pair to the base. This creates a Lewis adduct, which is a compound that contains a covalent bond between a Lewis acid and a Lewis base.
Learning Lewis Acid and Lewis Base – Examples, Applications and Chemical Reactions?
- A Lewis acid is a molecule that can accept a pair of electrons from a Lewis base. A Lewis base is a molecule that can donate a pair of electrons to a Lewis acid.
- Some common Lewis acids include boron trifluoride (BF 3 ), aluminum chloride (AlCl 3 ), and hydrogen fluoride (HF).
- Some common Lewis bases include ammonia (NH 3 ), water (H 2 O), and methane (CH 4 ).
- When a Lewis acid and a Lewis base interact, they form a Lewis adduct.
- Some common Lewis adducts include aluminum hydroxide (Al(OH) 3 ), boron trifluoride ammonia (BF 3 ·NH 3 ), and hydrogen fluoride ammonia (HF·NH 3 ).
