Defining alternative groups
You can create alternative group definitions (R, G, etc.) that represent a set of substituents, each of which is used in
the query.
To define alternative groups:
1. Go to View>Other Toolbars>Query Tools to open the Query toolbar.
2. Click the Alternative Group query tool and drag with the tool to create an area large enough to draw the alternative
groups.
3. Type a title, such as R
1
, in the Alternative Group Title box, then draw the substructure fragments in the Alternative
Group box.
Tip: You can also draw the box afterward to enclose the list of alternative groups.
