Identify the activity of ammonia due to the presence of lone pair of electrons in it, from following.

Options

  1. AAct as a Lewis acid
  2. BAct as a Lewis base
  3. CAct as a reducing agent
  4. DAct as an oxidizing agent

Correct answer

B. Act as a Lewis base

Step-by-step solution

Ammonia ( NH₃ ) 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
