E2 elimination template
Premium template. Preview and edit it free in MolDraw; downloading and exporting it is part of MolDraw Pro.
Hydroxide removes a β-hydrogen as bromide leaves, giving propene.
Mechanism step by step
Concerted loss of H and Br: three curly arrows in one step
- Concerted elimination – Base takes H; C–H electrons form C=C; Br⁻ leaves
Key points
- Rate = k[base][R–X].
- H and the leaving group must be anti-periplanar.
- Strong, bulky bases favour E2 over SN2.
- Zaitsev product (more substituted alkene) usually dominates.
Drawn with 21 atoms, 5 arrows, 6 shapes – every one editable in MolDraw.

Frequently asked questions
Is the E2 elimination template free?
You can preview the E2 elimination template here and open and edit it in MolDraw for free. Downloading or exporting it is part of MolDraw Pro, together with the other premium templates.
Can I edit the E2 elimination template?
Yes. It opens as an ordinary MolDraw drawing, so every structure, arrow, label and colour can be changed, and you can add your own content around it.
Is the chemistry checked?
Every structure is checked with RDKit and every curly arrow passes MolDraw’s electron-flow audit. The sources used are listed on this page.
What is a curly-arrow mechanism template?
A ready-made drawing of a reaction mechanism in which curved arrows show where electron pairs move in each step. You can open it in MolDraw, change the substrate and reuse it.
