bronsted acid vs. lewis acid

[Josephine Lu 4L]

can a molecule be a bronsted acid and a lewis acid at the same time?

[Tony Ong 3K]

they're both the same thing, just defined differently
bronsted acid is proton donor while lewis definition of acid is electron acceptor

[Nick Bazett 1F]

Yes they can be both at the same time, however a substance does not always have to be both.

[RoopshaChatterjee 1G]

Because the definitions differ a little bit in that one is broader than the other, can one be a Bronstead acid without being a Lewis acid.

The Bronsted definition: an acid is a proton (H+ ion) donor, and a base is a proton acceptor;
The Lewis definition: an acid is an electron acceptor, and a base is an electron donor.
