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 ? b. Which are interhalogens or their anions ? c. Which are polyhalides ? d. Which are neither (a), (b), (c) or pseudohalogen or their anions ? e. Which are pseudohalogens of their anions ?

A : CN^(-) is pseudohalide . R : (CN)_(2) is pseudohalogen .
