Pseudohalogens or halogenides are comple...

Pseudohalogens or halogenides are complex molecules which behaves like halogen s. Among the following list `CN^(Theta)` (cyanide), `OCN^(Theta)` (cyanate), `SCN^(Theta)` (thio-cyanate), `SeCN^(Theta)` (selenocyanate), `TeCN^(Theta)` (tellurocyanate), `ONC^(Theta)` (isocyanate), `N_(3)^(Theta)` (azide), cyanogen `(CN)_(2)` oxycyanogen `(OCN)_(2)`, thiocyanogen `(SCN)_(2)`, telluroyanogen `(TeCN)_(2)`, azidecabon dislphide `(SCN N_(3),CICN, BrCN, ICN, ICI, IF_(7), IF_(5), I_(3)^(Theta), ICI_(2)^(Theta),I^(Theta), I^(o+), I_(3)^(o+))`.
a. Which are interpsedohalogents ?
