Create Reactions

From version 16.5.2 you can draw reactions in two modes.

  • the earlier used mode, where the + signs are placed automatically and

  • placing manually the reaction + signs.

You can change\reset the default automatic mode on The Preferences<Structure tab.

Only reaction containing a single reaction arrow can be interpreted chemically, consequently be saved in chemical formats.

Arrows interpreted chemically:

  • Retrosynthetic Arrow images/download/attachments/47420458/g-retrosynthetic-arrow24.png

  • Equilibrium Arrow images/download/attachments/47420458/g-equilibrium-arrow24.png

  • Resonance Arrow images/download/attachments/47420458/g-doublearrow24.png

Consequently, more arrows or

  • Dashed Arrow images/download/attachments/47420458/g-dashed-arrow24.png

  • Crossed Arrow images/download/attachments/47420458/g-crossed-arrow24.png

will not have chemical meaning. These arrows and + signs ( besides the molecules) can be formatted using the Edit<Format or the contextual menu.

No structure label(s) can be used to annotate unknown structures. These labels can be saved in .mrv, .skc and cdx. Empty .mol .rxn .rdf files generated after v. 15.11.23 are opened displaying a No Structure label on the canvas.

The graphical components of reactions can be aligned and distributed using the corresponding menu item of the Edit menu.

Analysis box containing chemical information an be added from the Structure menu or pressing the Ctrl+I shortkey.
