Question and Answer

The correct order of pseudohalide,polyhalide and interhalogen are 
(A) \(BrI^-_2, OCN^-,IF_5\)
(B) \(IF_5.BrI^-_2, OCN^-\)
(C) \(OCN^-, IF_5, BrI^-_2\)
(D) \(OCN^-, BrI^-_2, IF_5\)

Answer

Answer: D
Interhalogen are the compound of two halogens.
So \(IF_5\) is interhalogen.
\(OCN^-\) acts as halide but actually is not a halide .
So, \(OCN^-\) is pseudo halide
