Which of the following is not an electrophile?
Options
- ACN ⁻
- BBF ₃
- CNO ₂⁺
- DAlCl ₃
Correct answer
A. CN ⁻
Step-by-step solution
Electrophile is a species that forms bonds with nucleophiles by accepting an electron pair, because electrophiles accept electrons, they are Lewis acids. CN ⁻ is nucleophile, which is electron rich in nature and electrophile is electron deficient in nature and contain positive charge. BF ₃= Neutral electrophile or Lewis acid (electron deficient) NO ₂⁺= Electrophile AlCl ₃= Electrophile (electron deficient) Hence, only CN ⁻ is not an electrophile.
