Which one of the following sets correctly represents the increase in the paramagnetic property of ions

Options

A. `Cu^(+2) gt V^(+2) gt Cr^(+2) gt Mn^(+2)`
B. `Cu^(+2) lt Cr^(+2) lt V^(+2) lt Mn^(+2)`
C. `Cu^(+2) lt V^(+2) lt Cr^(+2) lt Mn^(+2)`
D. `V^(+2) lt Cu^(+2) lt Cr^(+2) lt Mn^(+2)`

Answer

C

Explanation

paramagnetic property depends upon the number of unpaired electrons, higher the no of unpaired electron, higher the paramagnetic property.
