Bond Menu

    This menu allows changing the type of a bond and makes bond properties available, for example, bold, topology, reacting center, and many more.

    Menu item Icon Description
    Type > Single Single bond icon Changes the selected bond type to Single.
    Type > Double Double bond icon Changes the selected bond type to Double.
    Type > Triple Triple bond icon Changes the selected bond type to Triple.
    Type > Aromatic Aromatic bond icon Changes the selected bond type to Aromatic.
    Type > Single Up Single up bond icon Changes the selected bond type to Single Up. (Active only in 2D.)
    Type > Single Down Single down bond icon Places Single Down type wedge bond on the canvas. Changes the selected bond type to Single Down. (Active only in 2D.)
    Type > Single Up or Down Single up or down bond icon Changes the selected bond type to Single Up or Down.
    Type > Double Cis or Trans Double cis or trans bond icon Changes the selected bond type to Double Cis or Trans.
    Type > Double C/T or Unspec Double c/t or unspec bond icon Changes the selected bond type to Double Cis/Trans or Unspec.
    Type > Single or Double Single or double bond icon Changes the selected bond type to Single or Double.
    Type > Single or Aromatic Single or aromatic icon Changes the selected bond type to Single or Aromatic.
    Type > Double or Aromatic Double or aromatic icon Changes the selected bond type to Double or Aromatic.
    Type > Any Any bond icon Changes the selected bond type to Any.
    Type > Coordinate Coordinate bond icon Changes the selected bond type to Coordinate.
    Bold Bold bond icon Changes the selected bond to Bold. For more information, see the Bold tool.
    Hashed Hashed bond icon Changes the selected bond to Hashed.
    Topology > None Topology none icon Unsets the bond topology property.
    Topology > In Ring Topology in ring icon Sets a bond property so that when the molecule is used as a query, the specified bond must be in a ring to score a hit.
    Topology > In Chain Topology in chain icon Sets a bond property so that when the molecule is used as a query, the specified bond must be in a chain to score a hit.
    Reacting Center > None Reacting center none icon Unsets reacting center query feature of the selected bond.
    Reacting Center > Center Reacting center center icon Sets reacting center query feature on the selected bond: the bond takes part in the reaction.
    Reacting Center > Make or Break Reacting center make or break icon Sets reacting center query feature on the selected bond: the bond is created or disappears in the reaction.
    Reacting Center > Change Reacting center change icon Sets reacting center query feature on the selected bond: the bond remains in the reaction, but its bond type changes, for example, from single to double.
    Reacting Center > Make and Change Reacting center make and change icon Sets reacting center query feature on the selected bond: currently it works exactly as Center.
    Reacting Center > Not Center Reacting center not center icon Sets reacting center query feature on the selected bond: the bond must not change in the reaction.
    Stereo Search Stereo search Uses stereo configuration of the specified double bond when this molecule is used as a query.
    Align > Horizontally N/A Alters the molecule so that the selected bond is oriented horizontally.
    Align > Vertically N/A Alters the molecule so that the selected bond is oriented vertically.
    Ligand order N/A Changes the order of the attachment of R-group ligands.
    Edit Properties N/A Bond properties can be edited from this menu.
