Question

$N{H}_3$ is not a base according to:

• A. Bronsted theory
• B. Lewis theory
• C. Arrhenius theory
• D. Lowry theory

Answer 1

The correct option is C Arrhenius theory

A) Bronsted bases are those which can accept $H^{+}$ species. $⟹H^{+}$ transfer

B) Lewis bases are those which can donate lone pairs. Every Bronsted base is a lewis base. $⟹e^{-}$ transfer

C) Arrhenius bases are those which donate $O{H}^{-}$ species. $N{H}_3$ doesn't have $-OH$ group to donate.

D) Lowry theory, $N{H}_3$ can be a base because it can accept $H^{+}$ and donate electrons. $⟹H^{+}$ transfer.

Option C is correct.
