Nucleophile — electron-pair donor

Nu:

Electrophile — electron-pair acceptor

R–C–LG

transition-state

Back-side attack

Description of this simulation

SN2 substitution, step 1 of 2: concerted transition state.

Quick test · 3 questions
1. Which statement is evidence from this simulation?
2. How should you test the effect of one control?
3. Why read the model notes?

Electron-pair movement

nucleophile lone pair → carbon bearing leaving group

concerted transition state

rate = k[substrate][nucleophile]

What this model shows — and what it simplifies

Educational Model

Curved arrows are a bookkeeping language for electron-pair movement through authored teaching mechanisms.

Where do we see this in real life?

Mechanism reasoning helps chemists choose substrates, solvents and conditions that favour substitution, elimination or addition products.
