Question

Among the properties given below:

$\left(A\right)$ Reducing

$\left(B\right)$ Oxidising

$\left(C\right)$ Complexing

The set of properties shown by $C{N}^{-}$ ion towards metal species are :

• A. $A,B$
• B. $B,C$
• C. $A,C$
• D. $A,B,C$

Answer 1

The correct option is C $A,C$

The set of properties shown by $C{N}^{-}$ ion towards metal species are reducing and complexing. $C{N}^{-}$ forms complexes with metals like $K_4\left[Fe\right(CN{)}_6]$ and also acts as a reducing agent.
