Lewis vs Bronsted

[Kyle Thorin]

What is the difference between Lewis and Bronsted Acids and Bases

[Kaylee Sepulveda 4G]

A lewis acid accepts an electron pair, while a lewis base donates an electron pair.

Bronsted/Lowry acids donate a proton and the bronsted/lowry base accepts a proton.

[Leslie Almaraz 4G]

What about the Arrhenius definition of acids and bases?

Is a lewis acid/base always a bronsted acid and vice-versa?

[Sadhana_Dicussion_4A]

Lewis acid is an electron pair acceptor and Lewis base is an electron pair donor. Bronstead acids are proton donors and Bronstead bases are proton acceptors.

[kendal mccarthy]

Lewis acids are lone pair acceptors. Lewis bases are lone pair donors. Bronsted acids are H+ donors. Bronsted bases are H+ acceptors. Bronsted acids are most always the same as Lewis bases because they always accept a proton by donating a lone pair. Bronsted acids are a special kind of Lewis acid because the H+ part of the bronsted acid is the Lewis acid, not the whole compound, because only the H+ accepts a lone pair, not the whole Bronsted compound.

How are some molecules Lewis acids but not Bronsted acids?

[Ashley Kim 3F]

Some molecules may be Lewis acids but not Bronsted acids because they have the ability to accept a lone pair of electrons, but do not have a proton to donate.
