`Na^(+),Fe^(+3),CO^(2+),Cr^(+2)`

A

`Na^(+) lt CO^(2+) lt Cr^(+2) lt Fe^(3+)`

B

`Fe^(3+) lt Cr^(2+)ltCo^(+2)ltFe^(3+) lt Na^(+)`

C

`Na^(+)ltCr^(2+)ltCo^(+2)ltFe^(3+)`

D

`Na^(+)ltFe^(3+)ltCr^(2+)ltCo^(+2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Na^(+)ltCo^(2+)ltCr^(2+)ltFe^(3+)`
Higher the number of unpaired electron will be magnetic moment .
