Question

Determine what the spin state of each complex will be using the spectrochemical series along with your chemical intuition. Please explain any complexes that may be difficult to determine. You may assume any 6-coordinate complex has octahedral symmetry and any 4-coordinate complex has tetrahedral symmetry.

a. VCI3(H20)3
b. Fe(NH3)23

Answer 1

A) high spin complex

B) low spin complex

Step-by-step explanation:

A) VCI3(H20)3 is a high spin complex and this is because the complex has a weak field ligands all . this weak field ligands makes it impossible for pairing to take place

B) Fe(NH3)23 is a low spin complex and this is because the complex is made up of strong field ligands, this strong field ligands makes it possible for paring to take place

note : Ligands in which its donor atoms are ; Nitrogen,phosphorous or carbon are considered strong ligands
