Query indicators
Query indicators display the atom properties that you assign to a structure, as shown below. If more than one property
is assigned, an indicator for each property appears adjacent to the atom.
Figure 11.2: This structure illustrates several possible atom properties that can be assigned.
The list below describes each indicator:
*—Substituents: Free Sites (followed by the number of free sites)
U—Substituents: Up to (followed by the maximum number of substituents)
X—Substituents: Exactly (followed by the number of substituents)
H—Implicit Hydrogens. See "Implicit hydrogens " on page 204.
R—Ring Bond Count
S—Unsaturation
C—Reaction Change
T—Reaction Stereo
L—Translation
(none)—Abnormal Valence
Viewing indicators for an atom or bond
Except for the substituents query properties, the characters indicate that a given property is applied, but not the value
of that property.
To find the value of a query property setting:
1. Select the atom.
2. Do one of the following:
Select the atom, right-click, point to an atom, and point to the appropriate property.
Go to Structure>Properties and view the settings on the Atom Properties tab.
To display query indicators for an atom or bond:
1. Right-click the atom or bond.
2. Choose Show Query Indicator on the context menu.
