Lewis vs. Bronsted

[Eesha Chattopadhyay 2K]

What exactly is the difference between Lewis acids/bases and Bronsted acids/ bases?

[205296774]

Lewis Acids accept electron pairs while Lewis Bases donate electron pairs. Bronsted Acids donate a proton and Bronsted Bases accept protons.

Hope this helps!

There are two different definitions of acids and bases. The Lewis definition of an acid is that is a species that accepts an electron pair. The Bronsted definition of an acid is that an acid is a proton donor. The Lewis definition of a base is a species that donates an electron pair. The Bronsted definition of a base is that a base is a proton acceptor.

A Lewis acid is defined as accepting an electron pair while a bronsted acid is defined as donating a proton. A lewis base is defined as donating an electron pair while a bronsted base is deifned as accepting a proton. Note that in water, the "proton" defers to a hydronium ion such as in the case of HCl reacting in water.
