Edexcel IAL Chemistry AS 10.4 Nucleophiles
Look for an available lone pair rather than a negative charge alone, then identify the δ+ or positively charged atom that can accept that pair.
How this is tested
- Select a nucleophile by finding an available lone pair that can attack an electron-deficient atom.
- Reject species such as NH₄⁺ that lack an available lone pair despite containing nitrogen.
