Bronsted vs Lewis acids

Postby Kaleb Tesfaye 1I » Thu Jun 07, 2018 9:35 am

Is there any correlation between the definition of bronsted acids and Lewis acids. I can't seem to relate the two definitions.

The definition of a Lewis acid is an electron pair acceptor. The definition of a Bronsted acid is a proton donor. On page 609 of the textbook, it says that "a Bronsted acid is a supplier of one particular Lewis acid, a proton". This makes sense since the Bronsted acid donates the electron and the Lewis acid accepts the electron pair.

A Bronsted acid is a proton donor while a Lewis acid accepts an electron pair.
A Bronsted base is a proton acceptor while a Lewis base donates an electron pair.

Hope this helped!

lEwis Acids are Electron Acceptors.
lewis bases are electron donors.

brOnsted aciDs are prOton Donors.
bronsted bases are proton acceptors.

An easy way to memorize it is to look at the capitalized letters and correlate them with each other.
It is interesting because in a process like H+ becoming H, the H+ is an acid and H is the base. Each is either one or other.
