PhCOPh

Answer 1

Hint: The international Union for Pure and Applied chemistry is an international non-governmental organization designed to address the problems or issues concerning chemical science around the world. Its primary goal is to promote global cooperation in the chemical sciences.

Complete step by step answer:
Basically, the aim of the nomenclature IUPAC program is to create an international standard for designating compounds to promote communication. Moreover, the purpose of this system is to give a unique and unambiguous name to each structure and to compare each name with a unique structure.
According to the guidelines, the nomenclature of the compounds must follow some certain rules such as
-Longest chain rule
-Longest set of locants
-Multiple instances of the same substituent
-Naming of different substituents
-Naming of different substituents present at the same position
-Naming complex substituents
Now, the general format of the IUPAC name of the compound can be written as:
Locant + prefix + root + locant + suffix
The word root indicates the total number of carbon atoms present in the longest carbon chain. Moreover, suffix is usually a functional group belonging to the molecule which follows the root of the name and prefix are added prior to the root of the compounds.
Now, according to the given rules, the IUPAC name of the compound PhCoPh is Diphenylmethane and its common name is Benzophenone.

Note:
The IUPAC nomenclature guidelines are not always followed by chemists because some compounds have very long and extremely tedious names as per the IUPAC guidelines.
