Question

All bronsted bases are Lewis bases. Explain.

Answer 1

Explanation:

• Any substance which can donate a pair of an electron can easily accept a proton. Thus all Bronsted bases are all Lewis bases. ... HCl, H2SO4 are Bronsted acids because they can donate protons, but they cannot accept a pair of electrons to form a coordinate bond, therefore, they are not Lewis acids.

Answer 2

All Bronsted bases are Lewis bases because bronsted base can accept proton and also donate pair of electrons to Proton so that it is a Lewis base

Eg :- Ammonia can accept proton and also donate a pair of electrons to Proton. It is a Lewis base and bronsted base
