Which of the following is a nucleophile?
- A \(\mathrm{BH}_{3}\)
- B \(\mathrm{NH}_{3}\)
- C \(\mathrm{AlCl}_{3}\)
- D All of these
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.
