Which of the following is low spin complex?
A low spin (or spin-paired) complex, such as [Co(NH3)6]3+ is one in which the electrons are paired up to give a maximum number of doubly occupied d orbitals and a minimum number of unpaired electrons. Usually inner orbital complexes (d2sp3) are low-spin (or spin paired) complexes.
Which of the following is a high spin complex?
Only complex [Cr(gly)3] is a high spin complex because it contains a weak field ligand and these type of ligands can not pair up the unpaired electrons while in other options there are atleast one strong field ligand. Hence,option A is correct.
Which of the following complex is not a low spin complex?
Thus the correct answer is C.
Is oxalate high spin or low spin?
The result of these differences for the d-orbitals is an energy difference between the dz2 and dx2-y2 orbitals compared to the dxy, dyz and dxz orbitals….Crystal Field Theory (CFT), An Introduction.
| K3[Fe(oxalate)3] 3H2O | K2[CuCl4] | |
|---|---|---|
| High Spin/Low Spin | High Spin | Not relevant (all High spin) |
| # of unpaired electrons | 5 | 1 |
Is Water high or low spin?
Water is a weak ligand and the energy gap between d to d* level is small. Hence the d electrons will ignore the small energy difference and be filled in the same way as in gaseous Fe3+ cation, where electrons will occupy orbitals singly and with parallel spins.
Which is a diamagnetic complex?
(Fe(CN)6)4− complex is diamagnetic because contains no unpaired electrons, this can be explained based on the properties of ligands and based on the spectrochemical series CN− ligand will have stronger field than F− ligand so the cyanide complex have a greater energy difference in the d orbital.
Why is a complex diamagnetic?
Many transition metal complexes have unpaired electrons and hence are paramagnetic. Molecules such as N2 and ions such as Na+ and [Fe(CN)6]4− that contain no unpaired electrons are diamagnetic. Diamagnetic substances have a slight tendency to be repelled by magnetic fields.
Which complex is diamagnetic mno4?
As a d 1 ion,MnO42- has an unpaired e- and hence is paramagnetic and MnO4- has d2 in the outer most configuration and hence is diamagnetic (has no unpaired e- on outermost shell).
How do you identify a diamagnetic complex?
Molecules such as N2 and ions such as Na+ and [Fe(CN)6]4− that contain no unpaired electrons are diamagnetic. Diamagnetic substances have a slight tendency to be repelled by magnetic fields. When an electron in an atom or ion is unpaired, the magnetic moment due to its spin makes the entire atom or ion paramagnetic.
Which of the following complex is paramagnetic in nature?
hence , [NiCl4]2− is paramagnetic in nature.
How do you find the magnetic nature of a complex?
The magnetic properties of a compound can be determined from its electron configuration and the size of its atoms. Because magnetism is generated by electronic spin, the number of unpaired electrons in a specific compound indicates how magnetic the compound is.
Why the complex potassium Trioxalatoferrate is paramagnetic in nature?
Also, NH3 is a weak field ligand that does not cause the pairing of the electrons in the 3d orbital. Therefore, it undergoes d2sp3 hybridization and the electrons in the 3d orbitals remain unpaired. Hence, it is paramagnetic in nature. It causes the pairing of the 3d orbital electrons.
Which of the following complex ion has maximum paramagnetic nature?
So, [Fe(CN)6]3− has maximum paramagnetic character.
Which of the following is inner orbital complex?
[Co(NH3)6]+ is an inner orbital complex as wall as diamagnetic m behaviour (due to absence of unpaired electrons). [Zn(NH3)6]2+→sp3d2 hybridisation (outer orbital complex and diamagnetic in nature.
Which is not inner orbital complex?
The first two complexes are paramagnetic corresponding to one unpaired electron while the third one is diamagnetic. Such complexes are unsually formed with strong field ligands [Co(H2O)6]2+ is an outer orbital complex involving sp3d2 hybridization. Note that H2O is a weak field ligand.
What will be the correct representation of inner orbital complex?
The hybridisation of the complex [Co(NH3)6]+3 would be d2sp3 and hence it will be an inner orbital complex. Since the complex [Co(NH3)6]+3 is both an inner orbital complex and diamagnetic, this option is correct.
What do you mean by inner orbital complex?
Inner orbital complexes are coordination compounds composed of a central metal atom having hybridization of the atomic orbitals including d orbitals of inner shell and s, p orbitals from the outer shell. Therefore, these d orbitals are in a lower energy level than s and p orbitals.
What are inner and outer orbital complexes give examples?
Explain the following terms: (i) Inner orbital complex and (ii) outer orbital complex. i) Inner orbital complexes that use inner d- orbitals in hybirdisation; for example [Co(NH3)]3+ is inner orbital because the complex is using inner d-orbital therefore it’s hybridization is d2sp3. Also know as low spin complex.
What is the difference between inner and outer orbital complexes give examples?
Inner Orbital Complexes: Inner orbital complexes are composed of metal atoms that use inner shell d orbitals for the hybridization in the central metal atom. Outer Orbital Complexes: Outer orbital complexes are composed of metal atoms that use outermost shell d orbitals for the hybridization in the central metal atom.
What are inner and outer orbital complexes explain with examples?
The complexes formed, if have inner d orbitals are called low spin complexes or inner orbital complexes and if having outer d orbitals are called high spin or outer orbital complex. The inner d orbitals are diamagnetic or less paramagnetic in nature hence, they are called low spin complexes.
Which of the following electronic configuration is not possible for inner orbital octahedral complex?
Thus, d3 and d8 configuration of octahedral complex(es), cannot exist in both high spin and low spin forms.
What are T2g and eg orbitals?
Eg orbitals are axial and the ligands are approaching the metal ion axially in an octahedral complex. T2g orbitals are arranged in between axes and affected less. So more affected eg is raised in energy and t2g is lowered in energy to keep conservation of energy principle.
