Answer 2

Answer:

NH3 behaves both as acid and as base.

⇒So, the answer is (b) NH3.

Explanation:

NH3 is an amphoteric which means it has H atoms that can be donated as H+ ions and act as acids also lone-pair electrons that can accept an H+ and thus act as bases.

In this manner NH3 can act as an acid or a base.

• The nitrogen atom in NH3 has a lone pair of electrons which can be donated to suitable Lewis acid. So, NH3 can act as a Lewis base.
• NH3 is the chemical formula of ammonia.
• It is a chemical compound composed of one nitrogen atom and three hydrogen atoms.
• It is also known as Hydrogen Nitride, Nitrosil, and Vaporole.
• Nh3 is a colourless gas that is lighter than air, and can be easily liquefied.
• NH3 normally encountered as a gas and has a strong odour.
