Which one of the following species is not a pseudohalide?
A.
$$CN{O^ - }$$
B.
$$RCO{O^ - }$$
C.
$$OC{N^ - }$$
D.
$$NN{N^ - }$$
Answer :
$$RCO{O^ - }$$
Solution :
The species called as pseudohalide ions are these are monovalent and made by electronegative atoms. They possess properties similar to halide ion. The
corresponding dimers of these pseudohalide ions are called pseudohalogens. $$RCO{O^ - }$$ is not is pseudohalide.
