Nucleophiles & Electrophiles

Electron-rich meets electron-poor

An interactive lesson with 5 steps, about 5 minutes: you predict, drag and solve, with instant feedback on every answer. It runs in your browser and needs JavaScript.

What you’ll learn

• Nucleophiles share electrons (lone pairs, negative charge, π bonds).
• Electrophiles accept them (positive charge, empty orbital, δ+ atoms).
• Arrows run from nucleophile to electrophile.

Steps

1. Rich and poor
2. Spot the nucleophiles
3. The electrophilic carbon
4. Carbonyl carbon
5. Sort them
