Which of the following statements is/are true ?

A

In ferrocyanide ion, the effective atomic number is 36

B

Chelating ligands are atleast bidentate ligand

C

`[CrCl_(2)(CN)_(2)(NH_(3))_(2)]and[CrCl_(3)(NH_(3))_(3)]` both have `d^(2)sp^(3)` hybridisation

D

all

Text Solution

Verified by Experts

The correct Answer is:
D
EAN = 26 - 2 + 6(2) = 36
(b) chelating ligands have to denote atleast 2 pairs of electrons
both `NH_(3)` and `CN^(-)` are strong field ligands.
Ferricyanide ion has 1 unpaird electron
