a molecule drawing tool for the educator or student

Simple and flat, chemical structures made with this program are designed to be compatible with a paper surface rather than to compete with 3D models.


Help Topics are accessible from the Menu
Undo is available (command Z) ["Edit" Menu]
Viewing styles may be changed ["View" Menu]
Molecules may be Rotated ["Edit" Menu]
Any atom may be drawn and then changed to an different element.

  • Novice and Expert Modes
  • Quickly fill all open valencies with Hydrogen atoms
  • Quickly draw predefined three to six membered aliphatic rings plus benzene
  • Fuse rings for the above ring types
  • Remove an atom from a molecule (except from within rings)
  • Number atoms sequentially
  • See more features in the supporting web page.

    Once complete, flatMol molecules may be printed, saved or saved as a pict. file.
    Once saved as a pict. file, they may easily be copied or dropped into a word processor or test program.

    This program is designed to keep things simple; complicated ring structures or structures involving unusual bonds may not be able to be drawn here at all. I have chosen to disallow features such as unusual bonding or removal of random atoms within a ring group to keep other features ( such as rotation ) working properly.

  • What's New
    New Bond options; Aromatic, Hydrogen and Out of Plane bonding in expert mode.
    New Hydrogen options: add regular hydrogen atoms for emphasis in addition to the original small "fill in" hydrogens.
