How this entity was disambiguated
This entity first appeared as the object of triple T10656966 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Etter hydrogen-bond rules Context triple: [Margaret C. Etter, knownFor, Etter hydrogen-bond rules]
-
A.
The Nature of the Chemical Bond
The Nature of the Chemical Bond is a landmark chemistry book by Linus Pauling that systematically explains chemical bonding using quantum mechanics and became one of the most influential scientific texts of the 20th century.
-
B.
Heitler–London theory of the chemical bond
The Heitler–London theory of the chemical bond is an early quantum mechanical model that explains covalent bonding by treating it as the result of electron exchange and spin pairing between atoms.
-
C.
Hammett acidity function
The Hammett acidity function is a quantitative measure of superacidity in very strong acid solutions, extending the concept of pH to media where conventional acidity scales fail.
-
D.
Longuet-Higgins theorem in molecular symmetry
The Longuet-Higgins theorem in molecular symmetry is a fundamental result in theoretical chemistry that relates molecular symmetry properties to electronic state degeneracies and the occurrence of phenomena such as the Jahn–Teller effect.
-
E.
Westheimer rules in physical organic chemistry
Westheimer rules in physical organic chemistry are empirical guidelines that relate molecular structure and substituent effects to reaction rates and mechanisms, helping to rationalize and predict reactivity patterns.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
