Which of the following is a nucleophile?

  1. A \(\mathrm{BH}_{3}\)
  2. B \(\mathrm{NH}_{3}\)
  3. C \(\mathrm{AlCl}_{3}\)
  4. D All of these
Verified Solution

Answer & Solution

Correct Answer

(B) \(\mathrm{NH}_{3}\)

Step-by-step Solution

Detailed explanation

Nucleophiles (ie, nucleus loving) are the species that have atleast one lone pair of electrons for donation, ie, they can also be called Lewis bases. Among the given, \(\mathrm{BH}_{3}\) and \(\mathrm{AlCl}_{3}\), being electron deficient, behave like electrophiles while \(\ddot{\mathrm{N}} \mathrm{H}_{3}\), due to the presence of a lone pair over \(\mathrm{N}\), is a nucleophile.
