Vedclass · Answer

(B) To determine the $IUPAC$ name,we identify the substituents on the benzene ring: an ethyl group $(-C_2H_5)$,a fluoro group $(-F)$,and a nitro group $(-NO_2)$.According to $IUPAC$ rules,we number the ring to give the lowest possible locants to the substituents.If we start numbering from the fluoro group as $1$,the nitro group is at $2$,and the ethyl group is at $4$.The set of locants is $(1, 2, 4)$.Alphabetical order of substituents: ethyl,fluoro,nitro.Therefore,the name is $4-$ethyl$-1-$fluoro$-2-$nitrobenzene.

The correct $IUPAC$ name of the given compound is:
