Lewis Acids

[Amy Shimizu 1J]

Could someone clarify the difference between a Lewis acid, a Bronsted acid, and an Arrhenius acid? Specifically, the textbook stated how a Lewis acid differs because it is the actual proton, which I am a little confused about as well.

A Lewis acid accepts an electron pair. A Bronsted acid donates a proton, usually a H+. An Arrhenius acid is just a compound that increases the H+ concentration in solution. I think we mainly just focus on Lewis and Bronsted in 14a. The Lewis definition is more general than the Bronsted definition

[OishiBhattacharya2K]

An arrhenius acid: gives off H+ while an arrhenius base: gives off OH-.
A Bronsted-acid is a proton donor while a bronsted-base is a proton acceptor.
Lewis acid is an electron acceptor while a Lewis base is an electron donor

[Jahnavi Srinivas 2H]

A lewis acid is an electron pair acceptor. A Bronsted acid is a proton donor (H+). Finally, an Arrhenius acid contains hydrogen and releases H ions in water.

In Lewis Acids and Bases, the structure is classified depending on its ability to accept or donate electrons.
Lewis Acid: Accepts a pair of electrons
Lewis Base: Donates a pair of electrons
On the other hand, Bronsted acids and bases are classified on their ability to donate or accept protons.
Bronsted Acid: Donates protons
Bronsted Base: Accepts protons
