Question

Select the species which can function as Lewis base, Bronsted acid and Bronsted base ?

• A. $N{H}_3$
• B. $H^{-}$
• C. $C{l}^{+}$
• D. $F^{-}$

Answer 1

The correct option is A $N{H}_3$

Since Lewis base $=$ $e^{-}$ donor

Bronsted acid $=$ $H^{+}$ donor

Bronsted base $=$ $H^{+}$ acceptor

In $N{H}_3$, nitrogen have lone pair of electron, thus it can act as a Lewis base.

It can also accept $H^{+}$ ion to form $N{H}_4^{+}$ ion. Thus it can act as a Bronsted base.

Similarly, it can also lose $H^{+}$ ion to act as a Bronsted acid.
