The diamagnetic ion is

`V^(2+)`

`Cr^(2+)`

`Ti^(+3)`

`Sc^(3+)`

Text Solution

Verified by Experts

The correct Answer is:

Electronic configuration of ions given are as
`21Sc^(3+), 3d^(@)4s^(@)`
`22Ti^(3+),3d^(1)4S^(@)`
`23V^(2+),3d^(3)4S^(@)`
In `Sc^(3+)` ion, all electrons are paired and hence it diamagnetic.

Which of the following is a diamagnetic ion: (Atomic numbers of Sc, V, Mn and Cu are 21, 23, 25 and 29 respectively)

`V^(2+)`

`Sc^(3+)`

`Cu^(2+)`

`Mn^(3+)`

Assertion : Cuprous salts are diamagnetic in nature. Reason : Cu^(+) ion has filled 3d-orbitals.

If both assertion and reason are correct and reason is correct explanation for assertion.

If both assertion and reason are correct but reason is not correct not correct explanation for assertion.

If assertion is correct but reason is incorrect.

If both assertion and reason are incorrect.

The diamagnetic species is

`[Ni(CN)_(4)]^(2-)`

`[NiCl_(4)]^(2-)`

`[CoCl_(4)]^(2-)`

`[CoF_(6)]^(2-)`
