What is the hybridization of Cobalt?

Therefore, Cobalt can undergo d2sp3hybridization. Hence, it is an inner orbital complex.

What is hybridization of CO CN 4 2?

The empty 4s and three 4p orbitals undergo sp3 hybridization and form bonds with CO ligands to give Ni(CO)4. Thus Ni(CO)4 is diamagnetic. * In [Ni(CN)4]2-, there is Ni2+ ion for which the electronic configuration in the valence shell is 3d8 4s0. * In presence of strong field CN- ions, all the electrons are paired up.

Why is nicn4 square planar?

why [Ni (CN)4]-2 has a square planar structure?? CN- is a strong field ligand and thus all electrons get paired of nickel which is in +2 state in the compound. With one orbial of 3d, 4s and two 4p it makes the stable compound having dsp2 hybridization resulting in square planer structure not tetrahedral.

Why is dsp2 square planar?

As Cyanide is a strong field ligand, it pairs up the electrons in Ni2+ and makes available one inner 3d orbital. The orbitals participating are 3d, 4s, and 4p resulting in hybridization dsp2. The shape is square planar.

What is the hybridization of PdCl4?

Thus it is dsp2 hybridisation which is involved in the formation of (PdCl4]2- ion i.e. 4-coordinated complexes of Pd(II) have square planar geometry with n = 0 (diamagnetic).

What is hybridization of AuCl4?

Hybridization of [AuCl4]^ is sp^3 .

Why is Ni CN 4 2 square planar but Ni Co 4 is tetrahedral?

There is sp3 -hybridisation in Ni(CO)4. Hence it has tetrahederal structure. Oxidation state of Ni in [Ni(CN)4] 2– is +2 and Cl– ion is weak ligand. There is dsp2– hybridization in [Ni(CN)4]2– and it has square planar structure.

What is the shape of NiCN4?

The atomic number of Ni is 28 and its valence shell electronic configuration is 3d8 4s2. Ni is in +2 oxidation state in the complex [Ni(CN)4]2–. Hence, [Ni(CN)4]2– is dsp2 hybridised and it is square planar in shape.

Which complex has square planar dsp2?

Tetrahedral is sp3 and Square planar dsp2. One example is Ni(CN)4 is square planar (evidence is from the fact that it is diamagnetic).

Why Ni CN 4 2 is square planar but nicl4 2 is tetrahedral?

There is sp3 -hybridisation in NiCO4. Hence it has tetrahederal structure. Oxidation state of Ni in [NiCN4] 2– is +2 and Cl– ion is weak ligand. There is dsp2– hybridization in [NiCN4]2– and it has square planar structure.

How many hybrid orbitals are there in sp2 hybridization?

All the three hybrid orbitals remain in one plane and make an angle of 120° with one another. Each of the hybrid orbitals formed has 33.33% s character and 66.66% ‘p’ character. The molecules in which the central atom is linked to 3 atoms and is sp2 hybridized have a triangular planar shape. Examples of sp 2 Hybridization

What is the hybridization of planar trigonal planar?

Trigonal planar: Three electron groups are involved resulting in sp 2 hybridization, the angle between the orbitals is 120°. Tetrahedral: Four electron groups involved resulting in sp 3 hybridization, the angle between the orbitals is 109.5°.

Which d orbitals are available for hybridization in co-ordination complex?

Short Answer and Trick: If the ligands in the co-ordination complex are strong field ligand then the inner d orbitals will be available for hybridization because of induce pairing. In case of weak field ligands there will be no pairing and the outer d orbitals will participate in the process of the hybridization.

Can we predict the hybridisation of a complex on crystal field theory?

Can we predict the hybridisation of a complex (square planar or tetrahedral) on the basis of crystal field theory? CFT doesn’t actually provides knowledge about geometry but can provide when you have knowledge about its magnetic properties.
