Element selection

The element selection lets you choose which element you want to draw with. You can either chose between C, H, N, O, P, S, or you can click on PSE to open up a periodic table and select any other element from there.

Undo/Redo Arrows

Next to the element selection, you will find the undo and redo buttons.

Bond tools

The bond tools allows you to select between different types of bonds to draw with or change existing bonds.

Aingle bond tool Add single bonds. By clicking on a existing bond, the bond order is increased.
Double bond tool Add double bonds. By clicking on a existing double bond, the style is changed.
Triple bond tool Add tripple bonds.
Stereo bond tool
 Add stereo bonds. By clicking on a existing stereo bond, the orientation is changed.
Special bonds tool Add special bonds like dashed, wavy or delocalized bonds. Click on the disclosure triangle to choose from more special bond types in the popover. By continuously clicking on the special bonds button you can switch between the different special bond types.
specialbond_tools
  • dashed bond: by default the bond does not count in the calculation of free valences. This can be change by right-clicking on a existing dashed bond and enabling the attribute “bond count” in the bond attribute popover (see How to edit bonds).
  • wavy bond
  • delocalized bond by clicking on a existing delocalized bond you can change the orientation of the dashed bondline or hide it (e.g. to symbolzie delocalization by alternating double and single bonds). Delocalized bonds with only one bondline are highlighted with yellow color.
  • dative (corrdination) bond: by default the bond does not count in the calculation of free valences. This can be change by right-clicking on a existing dative bond and enabling the attribute “bond count” in the bond attribute popover (see How to edit bonds).

 
chain bond tool Add an atom chain. By dragging the further away, the chain gets longer. The orientation of the chain can be changed by holding the shift-key.

Ring system tools

In the ring system tools you will find simple ring systems that you can directly place into your sketch.

Cycloalkane Click on the disclosure triangle to choose from more ring types in the popover. By continuously clicking on the cycloalkane button you can switch between the different rings.
  • Cyclopropane
  • Cyclobutane
  • Cyclopentane
  • Cyclohexane (shown in toolbar)
  • Cycloheptane (7)
  • Cyclooctane (8)
  • Cyclononane (9)

 
Aromatic Ringsystems

 Click on the disclosure triangle to choose from more types of aromatic rings in the popover. By continuously clicking on the toolbar button you can switch between the different aromatic rings.

  • Benzene ring (shown in toolbar)
  • Benzene ring with delocalized ring
  • Naphthalene ring
  • Bipyridine
  • Porphyrin
Special ring systems

 Add special ring systems

  • add cyclohexane in chair conformation
  • add glucose in chair conformation

Reaction tools

Reaction arrow

 Click on the disclosure triangle to choose from more reaction arrows in the popover. By continuously clicking on the reaction arrow button you can switch between the different arrow types.

  • double arrow with open arrow tips
  • reaction mechanism arrow

By holding shift-key you can change the orientation of the arrow. By clicking on an existing arrow you can switch between open double barbed and single barbed arrows.

If you want to change the length of the arrow and form of the arrow tip, choose the selection tool in the toolbar and click on an existing arrow.
Special symbols

 Click on the disclosure triangle to choose from different special symbols in the popover. By continuously clicking on the special symbol button you can switch between the different symbols.

  • Plus symbol (for reaction equations, shown in toolbar)
  • positive charge symbol
  • negative charge symbol
  • single radical dot
  • double electron dots
Brackets

 Click on the disclosure triangle to choose from more bracket types in the popover. By continuously clicking on the bracket button you can switch between the different bracket types.

  • brackets (shown in toolbar)
  • single corner bracket
  • parentheses

To change the form of a bracket choose the selection tool in the toolbar and click on an existing bracket.
Drawing tools

 Click on the disclosure triangle to choose from more drawing element types in the popover. By continuously clicking on the toolbar button you can switch between the different drawing types.

  • circles and arcs (shown in toolbar)
