Which of the following is not nucleophile?
Correct answer: C. BF3
- A. H2O
- B. H2S
- C. BF3
- D. NH3
Explanation
BF3 (boron trifluoride) is not a nucleophile. A nucleophile is a species that donates an electron pair to form a new bond with an electrophile. In the case of BF3, it is an electron-deficient molecule and acts as a Lewis acid, accepting electron pairs rather than donating them. It typically acts as a Lewis acid by accepting a pair of electrons from a Lewis base to form a coordinate covalent bond.
