Bond orders: Valence
Connections : Total number of connections an atom makes
Ring count : Number of rings of which the atom is a part
Smallest ring size : Size of smallest ring of which the atom is a part
Ring bond : Total number of ring bonds the atom forms
Substitutions: Number of non-hydrogen substituents connected to the atom
Unsaturated: Makes the atom saturated or unsaturated
Aromaticity: Specifies whether the atom is aromatic (a) or aliphatic (A)
Bond Properties
Choose the bond of interest using the bond button.
Right click on the selected bond to open the menu
You can make bond order single, double, or triple by using the bond pull-down menu from the structure editor. This pull-down menu will also allow you to choose specific stereochemistry for a bond.
If you do not care about the stereochemistry or geometry of a bond, simply draw a plain single or double bond.
In coordination compounds, you should draw a single bond from all coordinating centers to the metal center.
Do not use the coordination bond; it does not work in new Reaxys!
Bonds can be: Single or Double Single or Aromatic Double or Aromatic Any
To change bond attributes after you’ve already drawn the bond right-click on the bond choose the Bond properties option, select Type, and choose the appropriate type of bond from resulting menu.
Topography
How to configure atoms in your molecule;
Two possible configurations Ring and Chain
In a substructure search in Reaxys, the database searches for either topology by default.
You can force the database to search for one or the other on individual bonds.
Right-click and select drop down menu to choose the bond's Topology
*By default, everything that looks like a ring will be in a ring, and everything that looks like a chain will be undefined
