Among the following ions, which one has the highest paramagnetism?

A

`[Cr(H_(2)O)_(6)]^(3+)`

B

`[Fe(H_(2)O)_(6)]^(2+)`

C

`[Cu(H_(2)O)_(6)]^(2+)`

D

`[Zn(H_(2)O)_(6)]^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
B

Thus `[Fe(H_(2)O)_(6)]^(2+)` is expected to be most paramagnetic, due to maximum number of unpaired electrons .
