Which of the following statements is not correct?

Options

A. The stability constant of `[CO(NH_3)_6]^(3+)` is larger than that of `[Co(NH_3)_6]^(2+)`
B. The cyano complexes are far more stable than those formed by halide ions
C. The stability of halide complexes follows in the order `I^(-) gt Br^(-) gt Cl^(-)`
D. The stability constant of `[Cu(NH_3)_4]^(2+)` is larger than that of `[Cu(NH_3)_4]^(2+)`

Answer

C

Explanation

The stability of halide complexes follows in the order `I^(-) lt Br^(-) lt Cl^(-)`
