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		Changes the selected bond type to Single.
Type > Double		Changes the selected bond type to Double.
Type > Triple		Changes the selected bond type to Triple.
Type > Aromatic		Changes the selected bond type to Aromatic.
Type > Single Up		Changes the selected bond type to Single Up. (Active only in 2D.)
Type > Single Down		Changes the selected bond type to Single Down. (Active only in 2D.)
Type > Single Up or Down		Changes the selected bond type to Single Up or Down.
Type > Double Cis or Trans		Changes the selected bond type to Double Cis or Trans.
Type > Double C/T or Unspec		Changes the selected bond type to Double Cis/Trans or Unspec.
Type > Single or Double		Changes the selected bond type to Single or Double.
Type > Single or Aromatic		Changes the selected bond type to Single or Aromatic.
Type > Double or Aromatic		Changes the selected bond type to Double or Aromatic.
Type > Any		Changes the selected bond type to Any.
Type > Coordinate		Changes the selected bond type to Coordinate.
Bold		Changes the selected bond to Bold. For more information, see the Bold tool.
Hashed		Changes the selected bond to Hashed.
Topology > None		Unsets the bond topology property.
Topology > In Ring		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		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		Unsets reacting center query feature of the selected bond.
Reacting Center > Center		Sets reacting center query feature on the selected bond: the bond takes part in the reaction.
Reacting Center > Make or Break		Sets reacting center query feature on the selected bond: the bond is created or disappears in the reaction.
Reacting Center > Change		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		Sets reacting center query feature on the selected bond: currently it works exactly as Center.
Reacting Center > Not Center		Sets reacting center query feature on the selected bond: the bond must not change in the reaction.
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.
