Description
|
|
There are too many bonds to this unlabeled Carbon.
|
Displayed for every unlabeled atom with more than 4 filled valences. Filled valences include sum of bond orders, charge, radicals, and free sites. Aromatic bonds count 1.5 each, rounded down unless it is the only bond to the atom. Charge is signed and includes charge implied by dative bonds. The Substituents query property treats Free Sites, Up to and Exactly the same way: an atom with 2 explicit bonds and "Substituents: Up To 3" or "Substituents: Exactly 3" or "Substituents: Free Sites 1" has three filled valences.
|
|
An atom in this label has an invalid valence.
|
Displayed in a variety of cases where ChemDraw cannot find a place to put a bond or cannot find a bond to put on an atom. Valid valences for each element are listed in the Isotopes Table file.
|
|
ChemDraw can't interpret this label.
|
Displayed when ChemDraw finds text that it cannot identify as an element, nickname, generic nickname, or alternative group name.
|
|
Parentheses don't match.
|
Displayed when parentheses cannot be matched into nested open-close pairs.
|
|
This label has conflicting or unassignable charges.
|
Displayed when a plus and minus charge have been assigned to the same element, charges have been assigned in more than one way, or a charge has been assigned to a nickname, generic nickname, or Alternative Group name.
|
|
Formula cannot be computed for queries.
|
Displayed for every label that contains a generic nickname, an element list or an alternative group. This is a status message only; analysis continues as if the problematic label were not selected.
|
|
Text not in Formula style won't be interpreted.
|
Displayed for the first caption that is not an atom label or Alternative Group name, and which contains any text not in Formula, Subscript, or Superscript style. This is a status message only, and appears only once regardless of how many captions are in the selection.
|
|
This named alternative group contains no attachment point.
|
Displayed for any structure within an Alternative Group Box where the structure lacks an attachment point. This is a status message only.
|
|
This named alternative group contains fragments with inconsistent valences.
|
Displayed for any Alternative Group Box whose contained structures have varying numbers of attachment points. Since all structures within an Alternative Group Box are to be used interchangeably, they must have the same number of attachments. This is a status message only.
|
|
This named alternative group contains no fragment.
|
Displayed for any Alternative Group Box that is empty. This is a status message only.
|
|
Part of a molecule is outside of the alternative group definition.
|
Displayed for any Alternative Group Box whose border crosses part of a structure. This is a status message only.
|
|
This isolated bond is probably not intended to have chemical significance.
|
Displayed for unlabeled single bonds unattached to other bonds. All bonds are interpreted chemically, usually as C2H6, and may cause unexpected results if intended as a graphical line only. This is a status message only.
|
|
The atom is very close to another atom or bond.
|
Displayed for any atom that is nearly touching another atom or bond but not bound to it. If a bond really was intended, the analysis of the structure produces incorrect results. This is s status message only.
|
|
The stereocenter has no stereobonds specified.
|
Displayed for any asymmetric center without attached wedged, hashed, dashed, or bold bonds. This is a status message only, and appears only when Show Stereochemistry is tuned on and there is at least one other wedged, hashed, dashed, or bold bond in the structure.
|
|
There is a valence and charge error somewhere in this aromatic system.
|
Displayed for any odd-membered ring drawn as a delocalized system (with a circle in the middle), where there is no corresponding associated charge. For example, a delocalized representation of cyclopentadiene must include either a negative charge or a multicenter attachment.
|
|
The stereocenter has conflicting or ambiguous stereobonds specified.
|
Displayed for any stereocenter (tetrahedral atom, asymmetric double bond, etc.) where the absolute stereochemistry cannot be determined from the structure as drawn. For example, this message would be shown for a carbon atom attached by bold bonds to four different ligands. This message is displayed only when Show Stereochemistry is also turned on.
|
|
This label has an unrecognized isotopic mass.
|
Displayed for every label that has a numeric superscript immediately preceding an atomic symbol, where the superscripted number does not correspond to a recognized isotope. For example, 24CH3.
