Organic molecules

Draw atoms and bonds, or load a molecule. Hydrogens fill in automatically from valence. The tool reads the structure you drew — it tells you what the graph contains, not whether the molecule is stable or easy to make.

Drag atoms to rearrange the drawing.

Library isomers of C₂H₆O

Constitutional isomers: same atoms, connected differently. Their properties can differ a lot. Stereoisomers (cis/trans, mirror images) are not distinguished here.

What this result is — and isn’t

User-built candidate. You drew or loaded this structure. A valid-looking drawing does not mean the molecule is stable, isolable or easy to make.
Rule-based assessment. Valences satisfied. Groups come from fixed pattern rules on the bond graph.
Database-supported material. Matched to “Ethanol” in a small built-in library of 63 molecules — not a chemical database. Confirm identity in PubChem or similar.
Calculated result. None. The 2D layout is only a drawing: no 3D geometry, energies, charges, pKa or spectra are calculated.
