    Potassium tetracyanidonickel (II), potassium tetrachloridonickel (II)
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
The coordination number of Ni2+is 4. [JEE-2006]NiCl2+ KCN (ex...
[Ni(CN)4]2−
The oxidation number of Ni is +2.
Atomic number = 28
Ni = [Ar]3d8 4s2 
Ni2+ = [Ar]3d8
NiCl2 + 4KCN -> K2 [Ni (CN)4] + 2KCl
A is K2 [Ni (CN)4]    
Potassium tetracyano nickelate(II) 

[NiCl4]2−
The oxidation number of Ni is +2.
Atomic number = 28
Ni= [Ar]3d8 4s2
Ni2+ = [Ar]3d8 
B is Tetrachlorido nickelate(II) ion
