    Which one of the following species is not a pseudo halide?

    A)  \[CN{{O}^{-}}\]           

    B)  \[RCO{{O}^{-}}\]

    C)  \[OC{{N}^{-}}\]                

    D)  \[NN{{N}^{-}}\]

    Correct Answer: B

    Solution :

    Those species are called as pseudohalide ions which are monovalent ion made by electronegative atom and possessing properties similar to halide ion. The corresponding dimers of these pseudohalide ions are called pseudohalogen. Therefore \[RCO{{O}^{-}}\] is not pseudohalide ion.
