# The limiting radius ratio of the complex [Ni(CN)4]2- is

Q: The limiting radius ratio of the complex [Ni(CN)4]2- is

(A) 0.225 – 0.414

(B) 0.414 – 0.732

(C) 0.155 – 0.225

(D) None

Solution: The complex [Ni(CN)4]2- is square planar. So, it has limiting radius ratio as octahedral structure i.e. 0.414 – 0.732

Ans: (B)
