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

A) high spin complex

B) low spin complex

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

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
