Naphthalene template
Premium template. Preview and edit it free in MolDraw; downloading and exporting it is part of MolDraw Pro.
The three Kekulé structures of naphthalene with the curly arrows that relate them; C1–C2 is double in two of three forms, C2–C3 in only one.
What the template shows
- Three Kekulé structures: the C1–C2 bond is double in two of them
- Resonance contributors
- Three Kekulé forms
- Only the middle form has a double bond between the two ring-fusion carbons.
- C1–C2 is double in two of the three forms and C2–C3 in only one, so C1–C2 is shorter (about 137 pm vs 142 pm).
- Ten π electrons over two rings (4n + 2, n = 2): naphthalene is aromatic, with less stabilisation per ring than benzene.
- Electrophiles attack C1 (α), where the intermediate keeps one intact benzene ring in more forms.
- Contributors are not in equilibrium: the real species is one hybrid of them · every part of this figure is editable
Drawn with 30 atoms, 8 arrows, 2 shapes – every one editable in MolDraw.

Frequently asked questions
Is the Naphthalene template free?
You can preview the Naphthalene 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 Naphthalene 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.
How are resonance structures shown?
Each contributor is drawn separately, joined by double-headed resonance arrows, with curly arrows showing how the electrons move from one contributor to the next.
