Answer:
The similarity between the IUPAC naming and the zoological taxonomic nomenclature is that both are used for naming and providing identity.
The difference between the IUPAC naming and the zoological taxonomic nomenclature system is that the IUPAC naming is the process of naming the chemical compounds. These names are published in the Nomenclature of Organic Chemistry (Blue book). On the other hand, the zoological taxonomic naming system is used for naming the animals. The International Code of Zoological Naming has published many research works related to zoological naming.
