For the same metal ion stability constant is more for the ligand

A

`I^(-)`

B

`Cl*(-)`

C

`F^(-)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
`F^(-)` is the smallest ion and hence stability constant is maximum as smaller size and high charge density enables greater stability of complex.

Stability constant is more for the metal ion

Stability constant is more for the complex:

Which of the following statements is correct with regard to complex ion ? . (a) complex ion consists of a central ion bonded to two or more donor ions or molecules usually does not dissociate into simple ions or molecules even in a solution and exhibits properties different from its constituent ions or molecules (b) The donor ions and molecues which coordinate with the central atom or ion a complex are called ligands The sum of the number of electrons pressent in the central metal ion or atom and those donated by the ligands is called the effective atomic number of the central metal aton and this number is usually the same as the atomic number of the next higher noble gas (d) All of these .

The correct order of stability of ions is :
