Nomenclature Of Coordination Compounds

In the given compound, we need to follow the IUPAC naming rules for substituted benzene rings. First, we number the benzene ring starting from the substituent with the highest priority (in this case, Nitro ). After the nitro group, the fluoro group ( ) is positioned in the 4th position and the ethyl group ( ) is in the 1st position.
Thus, the IUPAC name for this compound is 1-Ethyl-4-Fluoro-3-nitro benzene.
