DEFINITION

Classification: 524/360

Carbocyclic ring wherein one of the nuclear carbons thereof is double bonded directly to an oxygen atom so as to form a C=O group therewith, e.g., cyclohexanone, etc.:

(under subclass 359) Subject matter wherein the designated nonreactant material contains a carbocyclic ring wherein a single nuclear carbon atom of the carbocyclic ring is bonded directly to an oxygen atom by a double bond so as to form a C=O group therewith.
