What are Lewis Acids and Bases? How do they differ? Let’s find out!
In the Lewis theory of acid-base reactions, bases donate pairs of electrons and acids accept pairs of electrons.
A LEWIS ACID is a substance, such as the H+ ion, that can accept a pair of nonbonding electrons. So, a Lewis acid is an electron-pair acceptor.
A LEWIS BASE is any substance, such as the OH- ion, that can donate a pair of nonbonding electrons. So that Lewis base is an electron-pair donor.
Example:
The Aluminum ion is the metal and is a cation with an unfilled valence shell, and it is a Lewis Acid. Water has lone-pair electrons and is an anion, is a Lewis Base.
Another term that is connected to Lewis Acids and Bases:
Electrophilic- It happens in many of the reactions of compounds containing carbon-carbon double bonds.
