Question

Define inner and Outer Orbital Complexes!

Answer 1

✔️✔️✔️️Inner-orbital / low-spin /spin-paired complexes are those Complexes that use inner d-orbitals in hybridisation.

✔️✔️✔️Example, [Co(NH3)6]³+.


⭕️The hybradization of such compounds therefore is d2sp3 (D-Orbital filled at first).

⭕️They are known as low spin complexes.


✔️✔️✔️️Outer-orbital or high-spin or spin-free complexes are those Complexes that use outer d-orbitals in hybridisation!!!!!!!!!!

⭕️The hybradization of such compounds therefore is sp3d2 (D-Orbital filled at last).

⭕️They are known as high spin complexes.

✔️✔️✔️Example, [CoF6]³−.

Answer 2

$\huge\mathfrak\red{Answer :}$


$\huge\textbf{Inner Orbital Complex :}$


→ Inner Orbital Complex that uses inner d - orbital in hybridization... These are also known as Lower Spin Complex.


→ In this d - orbital used in the hybridization are in a lower energy level than s and p orbitals.


→ Examples :-

$[Fe(CN)_{6}]^{3-}$

$[Co(NH_{3})_{6}]^{3+}$

====================================


$\huge\textbf{Outer Orbital Complexes :}$


→ Outer Orbital Complex that uses outer d - orbital in hybridization... These are also known as Higher Spin Complex.


→ In this d - orbital used in the hybridization are in a same energy level as that of s and p orbitals.


→ Examples :-

$[CoF_{3}]^{3}$

$[CO_{6}]^{3-}$

=====================================
