Multiple choice

Which of the following complexes X, Y and Z is/are inert or labile? (X) [V(NH3)6]+++ (Y) = [Co(CN)6]3- (Z) = [Cr(CN)6]3-

  1. X and Y are inert, Z is labile.

  2. X and Z are labile, Y is inert.

  3. X is inert, Y and Z are labile.

  4. X is labile, Y and Z are inert.

  5. None of these

D Correct answer
Explanation

This option is correct, because the complex  X is labile, they contain the unhybridised metal orbital through which the ligand is attached more quickly in this orbital. But Y and Z are inert due to lack of availability unhybridised metal orbital the ligand cannot be attached in this orbital. (Lability shows more fast reaction and inert shows slow  reaction).
