Which of the following is an example of lewis base?a)ZnCl2b)BF3c)NH3d)...
< b="" />Lewis Base: NH3
NH3, also known as ammonia, is an example of a Lewis base. In order to understand why NH3 is a Lewis base, let's first define what a Lewis base is.
Lewis Base:
A Lewis base is a substance that can donate a pair of electrons to form a covalent bond. It acts as an electron pair donor.
Explanation:
NH3 has a lone pair of electrons on the nitrogen atom. This lone pair of electrons can be donated to another atom or molecule. When NH3 donates its lone pair of electrons to a Lewis acid, it forms a coordinate covalent bond, also known as a dative bond.
Examples of Lewis Acids:
- ZnCl2: ZnCl2 is an example of a Lewis acid. It can accept a pair of electrons from a Lewis base, such as NH3, to form a coordinate covalent bond.
- BF3: BF3 is also a Lewis acid. It has an empty p orbital that can accept a pair of electrons from a Lewis base.
- FeCl2: FeCl2 is not a Lewis base. It is a compound that contains a transition metal, iron, which typically acts as a Lewis acid by accepting electron pairs.
Therefore, among the given options, NH3 (option C) is the only example of a Lewis base as it can donate its lone pair of electrons to form a coordinate covalent bond.
