Diazonium salts are group of organic compounds that has common functional group R−N2+X−, where R is any organic group, e.g. alkyl or aryl. X′ is an inorganic group, e.g. halogens. (a) Aliphatic diazonium salts are not very stable. (b) Aniline can be converted into phenol via diazonium salt. (c) Aliphatic diazonium salts liberate nitrogen gas quantitatively. (d) Aniline can be converted into fluorobenzene via diazonium salt.
