Comprehension Type
Direction (Q. Nos. 16 and 17) This section contains a paragraph, describing theory, experiments, data, etc. Two questions related to the paragraph have been given. Each question has only one correct answer among the four given options (a), (b), (c) and (d).
Passage
When crystals of CuSO4 . 4NH3 are dissolved in water, there is hardly any evidence for the presence of Cu2+ ions or ammonia molecules. A new ion [Cu(NH3)4]2+ is furnished in which ammonia molecules are directly linked with the metal ion. Similarly, aqueous solution of Fe(CN)2 .4KCNdoes not give tests of Fe2+ and CN- ions but give test for new ion [Fe(CN)6]4- called ferrocyanide ion.
Q. 
The hybridisation and geometry and magnetic property of [Cu(NH3)4]2+ ion are
  • a)
    sp3, tetrahedral, diamagnetic
  • b)
    sp3, tetrahedral, paramagnetic
  • c)
    dsp2, square planar, diamagnetic
  • d)
    dsp2, square planar, paramagnetic
Correct answer is option 'D'. Can you explain this answer?

Answer:

The hybridisation and geometry of [Cu(NH3)4]2 ion can be determined by considering the coordination number and the nature of ligands attached to the central metal ion.

Hybridisation:
In [Cu(NH3)4]2, the coordination number of copper (Cu) is 4, which suggests sp3 hybridisation. This means that the copper atom in the complex is surrounded by four electron pairs, including four ammonia (NH3) ligands.

Geometry:
The sp3 hybridisation corresponds to a tetrahedral geometry. In a tetrahedral arrangement, the four ammonia ligands are arranged around the copper ion in a three-dimensional manner, with bond angles of approximately 109.5 degrees.

Magnetic Property:
To determine the magnetic property of [Cu(NH3)4]2, we need to consider the electronic configuration and the presence of unpaired electrons.

Cu2+ ion has an electronic configuration of [Ar]3d9. In [Cu(NH3)4]2, four ammonia ligands donate their electron pairs to the copper ion, resulting in the formation of coordinate bonds. As a result, the copper ion gains four additional electrons, leading to the formation of a d10 configuration.

In a d10 configuration, all the d orbitals are completely filled, and there are no unpaired electrons. Therefore, [Cu(NH3)4]2 is diamagnetic. Diamagnetic substances are those that do not contain any unpaired electrons and are not attracted to a magnetic field.

Summary:
- Hybridisation: sp3
- Geometry: Tetrahedral
- Magnetic Property: Diamagnetic

Overall, the [Cu(NH3)4]2 ion has sp3 hybridisation, a tetrahedral geometry, and is diamagnetic.
