All Lewis bases are in fact Bronsted bases-Explain.

Explanation

A substance which can accept proton is called a Bronsted base, while a substance which can donate a pair of electrons is called a lewis base. `NH_(3)` molecules can accept a proton. So, it is a bronsted base. Again, `NH_(3)` molecule donates a pair of electron in order to form a coordinate bond with a proton. so it also acts as a Lewis base. therefore, it can be inferred that a lewis base is basically a bronsted base.
