Bronsted Acids/ Lewis Acids

[Kelly Cai 4D]

In lecture, we discussed that Bronsted acids are proton donors while Lewis acids specifies that they accept electron pairs. Is this the main difference between these two? Are there other explanations and reasons that differentiate these two?

[Sadhana_Dicussion_4A]

A Bronstead-Lowry acid is defined as a substance that donates hydrogen ions, while a Bronstead-Lowry base accepts hydrogen ions. Another way of looking at it is Bronstead-Lowry acids are proton donors, while Bronstead-Lowry bases are proton acceptors. This is the main difference between the two.

[Matthew Chan 1B]

Lewis acids and bases are defined as being able to accept or donate electron pairs, while Bronsted Lowry acids and bases are defined as being able to accept or donate hydrogen ions (H+).
