Based on the CHEBI ontology perspective, alcohol is a class with subclasses like 'aromatic alcohol' which has subclasses like 'benzyl alcohols' which has subclasses like 'methylbenzyl alcohol' and so on.

These relationships seem worth capturing and subclass seems like a reasonable way to do it. If not, would another property be better?

Hi all,

why are both the subclass of and instance of properties set for the ethanol (showcase) item?
For me ethanol is a single concrete alcohol and it is not a class. There is only one ethanol, with a single chemical formula and structure, so only the instance of property is right for this item ?

Thank you
