Q.

Which of the following cannot function as an oxidising agent               [2024]

1 N3-  
2 SO42-  
3 BrO3-  
4 MnO4-  

Ans.

(1)              

In nitride ion (N3-), nitrogen is in its minimum possible oxidation state (-3) hence it cannot be further reduced. Thus N3- cannot act as an oxidizing agent.
