List I (Complex) | List II (Hybridization) | ||
A. | Ni(CO)4 | I. | sp3 |
B. | [Cu(NH3)4]2+ | II. | dsp2 |
C. | [Fe(NH3)6]2+ | III. | sp3d2 |
D. | [Fe(H2O)6]2+ | IV. | d2sp3 |
The correct answer is (C) : A-I, B-II, C-IV, D-III
For [Fe(NH3)6]+2,Δ0<P, hence the pairing of electrons does not occur in t2g.
Therefore complex is outer orbital and its hybridisation is sp3d2.
Match the following:
Ions | Properties |
I. Zn2+ | i. d8 configuration |
II. Cu2+ | ii. Colourless |
III. Ni2+ | iii. µ = 1.73 BM |
Codes:
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
