Valence Bond Theory(VBT) || Assumptions OF VBT and Important Aspects || Complexes with CN=4

Read the passage given below and answer the following questions : According to Valence Bond Theory, the metal atom or ion under the influence of ligands can use its (n-1)d, ns, np or ns, np, nd orbitals for hybridisation to yield a set of equivalent orbitals of definite geometry such as octahedral, tetrahedral, square planar and so on. These hybridised orbitals ar allowed to overlap with ligand rbitals that can donate electron pairs for bonding. Assertion (A) : In the square planar complexes, the hybridisation involved is dsp^(2) . Reason (R) : In [NiCl)_(4)]^(2-) . Here nickel is in +2 oxidation state and has the electronic configuration 3d^(8) .

These hybridised orbitals ar allowed to overlap with ligand rbitals that can donate electron pairs for bonding. Assertion (A) : [NiCl_(4)]^(2-) is an inner orbital complex. Reason (R) : An inner orbital or low spin or spin paired complex uses inner d orbitals of the metal ion for hybridisation.

These hybridised orbitals ar allowed to overlap with ligand rbitals that can donate electron pairs for bonding. Assertion (A) : In the diamagnetic octahedral complex, [Co(NH_(3))_(6)]^(3+) , the cobalt ion is in +3 oxidation state. Reason (R) : Six pairs of electrons, one from each NH_(3) molecule, occupy the six hybrid orbitals.

Which of the following two assumptions of the kinetic molecular theory do not hold good for real gases ? (i) There is no force of attraction between the molecules of a gas. (ii) The particles of a gas are always in constant and random motion in all possible directions in straight lines. (iii) At any particulat time, different particle sin the gas have different speeds and hence, different kinetic energies. (iv) The volume of the molecules of a gas is negligibly small in comparision to the space occupied by the gas.
