8.34 Calculate the number of unpaired electrons in the following gaseous ions: Mn3+ , Cr3+, V3+ and Ti3+. Which one of these is the most stable in aqueous solution?

8.34 From the table given below: Mn3+ : 3d4 unpaired electrons = 4 V3+ : 3d2 unpaired electrons =2 Cr3+ : 3d3 unpaired electrons= 3 Ti3+ : 3d1 unpaired electrons =1 Cr3+ is most stable in aqueous solution because of half filled d-orbital.

8.34 From the table given below:

Mn³⁺ : 3d⁴

unpaired electrons = 4

V³⁺ : 3d²	unpaired electrons =2
Cr³⁺ : 3d³	unpaired electrons= 3
Ti³⁺ : 3d¹	unpaired electrons =1

Cr³⁺ is most stable in aqueous solution because of half filled d-orbital.
