difference in acids

[Naana Boateng 1I]

Is a Bronsted acid/base the opposite of a Lewis acid/base?

[Christy Lee 2H]

Bronsted vs Lewis definitions are just focusing on different aspects of the molecule to determine acidity and basicity. Using either definition will lead to the same answer. For example, a Lewis acid is the same as a Bronsted acid, but if you say Lewis acid you are focusing on the ability of the molecule to accept an electron pair, whereas if you called it a Bronsted acid, you are focusing on the ability of the molecule to donate a proton. Therefore, they are not opposites, they are just different ways of defining an acid and a base but both lead to the same conclusions.

Are both definitions necessary for understanding acids and bases? Or will knowing one just be enough?

Also, the Lewis definition is more general than the Bronsted definition (not all Lewis acids are Bronsted acids, but all Bronsted acids are Lewis acids)
