electrophile and nucleophile

Question

Which of the following is a nucleophile?

RankGuru · Accepted Answer

**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), **$AlCl_3$** and **$BF_3$** (incomplete octet/Lewis acids) are all electrophiles.
