Identify the activity of ammonia due to the presence of lone pair of electrons in it, from following.
- AAct as a Lewis acid
- Correct answerBAct as a Lewis base
- CAct as a reducing agent
- DAct as an oxidizing agent
Solution
Ammonia ($NH_3$) has a lone pair of electrons on the nitrogen atom.
According to the Lewis concept of acids and bases, a species that can donate a pair of electrons is called a Lewis base.
Due to the presence of this lone pair, ammonia can donate an electron pair to electron-deficient species (Lewis acids).
Therefore, ammonia acts as a Lewis base.
Answer: Act as a Lewis base
According to the Lewis concept of acids and bases, a species that can donate a pair of electrons is called a Lewis base.
