Electrophile And Nucleophile
Easychemistry
Which of the following is a nucleophile?
Select the correct option:
Solution
Incorrect! Answer:
OH⁻
Nucleophiles (nucleus-loving) are electron-rich species that attack electron-deficient centers.
- They have either a negative charge or at least one lone pair of electrons.
- OH−: Has three lone pairs and a negative charge, making it a strong nucleophile.
- Electrophiles: Are electron-deficient. H+ (positive charge), AlCl3 and BF3 (incomplete octet/Lewis acids) are all electrophiles.
