Which one of the following is NOT a nucleophile?
Correct answer: B. BF3
- A. H2S
- B. BF3
- C. NH3
- D. CN-
Explanation
A nucleophile is an electron rich species and donates electron pairs to electron deficient species. On the other hand, Electrophiles are electron deficient that attract an electron. BF3 is an example of electrophile as it has an empty orbital that accepts electron pairs.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
