Assertion : Inner orbital complexes are...

Assertion : Inner orbital complexes are low spin complexes .
Reason : In low spin complexes , inner d-orbital (3d) is used in hybridisation .

A

If both Assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

if both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
A
Because inner d-orbitals is involved in hybridisation , pairing of electrons occur and hence due to less or no unpaired electrons the complexes are low spin complexes .

    Which of the following complex is a low spin complex ?

    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) : [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.
