Question

IUPAC does not recognise some functional groups and add them to the
name as prefix instead of suffix, these are nitro, nitroso, cyno ,
bromo and so on and treated as subtituents But in principle, they
are truly functional groups How many functional groups are treated
as substituents?

Dear student
Please find the solution to the asked query:

Depending upon the presence of other functional groups sometimes
some functional groups like that of halogens are treated as
prefixes
For example Fluoroacetic acid , Chlorobenzene, Iodobenzene etc
Sometimes for example in a compound of the type 4-bromo
3-methylheptanal
Here bromo is the prefix as methyl group , and aldehyde is present
in the compound

Cyano and isocyano are used as prefixes in compounds such as
Cyanonitrile
Nitro group is used as a prefix in compounds like Nitro methane
