Question

Inner and outer orbital complexes of Cr,Fe,Co,Ni and Cu?

Answer 1

Answer:

the relevant answer is :

The main difference between the inner as well as the outer orbital com[lexes of a particular element is based on hybridization of the particular atomic orbitals present of the central atoms which is present in the inner orbitals of these complexes and also it involves the inner shell "d-orbitals" .

whereas talking about the hybridization of the atomic orbitals present of the central atom of a metal of outer orbital complexes and it therefore involves the outermost shell present.

Examples are : Sc Ti V Cr Mn Fe Co Ni Cu Zn Y Zr Nb Mo Tc, etc.

Answer 2

Answer:

The inner and outer orbital complexes are

Explanation:

Electronic Configuration of elements are :

1. Cr

$[Ar] 3d^{5} 4s^{1}$

2. Fe

$[Ar] 3d^{6} 4s^{2}$

3. Co

$[Ar] 3d^{7} 4s^{2}$

4. Ni

$[Ar] 3d^{8} 4s^{2}$

5. Cu

$[Ar] 3d^{10} 4s^{1}$

Inner orbital Complexes :

• The coordination compounds which are composed of central metal atom and have hybridization for the atomic orbitals including orbital d of the inner shell and orbitals s, p of the outer shell are called as inner orbital complexes.
• In inner orbital complex, the central metal of atom uses d orbital of inner shell for hybridization.
• The d orbitals in inner orbital complex are low energy orbitals as compared to s and p orbitals.

Outer orbital Complexes :

• The coordination compounds which are composed of central metal atom and have hybridization for the atomic orbitals including s, p, and d of the outermost shell are called as Outer orbital complexes.
• In outer orbital complex, all orbitals have same energy level.
• In outer orbital complex, d orbital is located outside the s and p orbital.
