CH₃NO₂: an O⁻ lone pair forms N=O as the other N=O π bond moves onto its oxygen; the two N–O bonds are equal.

## What the template shows

- Two equivalent forms: N⁺ with one N=O and one N–O⁻
- Resonance contributors
- Two equivalent forms
- Both N–O bonds are the same length (about 122 pm) and each oxygen carries half a negative charge.
- Nitrogen keeps its octet and a formal positive charge in both forms; a structure with two N=O bonds would put ten electrons on N and is wrong.
- Nitroalkanes are acidic at the α-carbon (nitromethane pKa about 10): the nitronate anion is delocalised onto both oxygens.
- Contributors are not in equilibrium: the real species is one hybrid of them · every part of this figure is editable

Drawn with 8 atoms, 3 arrows, 2 shapes – every one editable in MolDraw.

## Frequently asked questions

### Is the Nitro group (nitromethane) template free?

You can preview the Nitro group (nitromethane) 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 Nitro group (nitromethane) 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.
