WebWhen naming a cyclic structure, the -OH is assumed to be on the first carbon unless the carbonyl group is present, in which case the later will get priority at the first carbon. When multiple -OH groups are on the cyclic structure, number the carbons on which the -OH groups reside. Remove the final e from the parent alkane chain and add - ol. WebJul 17, 2024 · If an atom A is double-bonded to an atom B, A is treated as being singly bonded to two atoms: B and a "ghost atom" that is a duplicate of B (has the same atomic number) but is not attached to anything except A. Ghost atoms are attached to resolve the triple/double bond. So according to CIP rules the two compounds can be resolved as
