Which one of the following transition metals ions is colourless in aqueous solution ?

A

`Ti^(4+)`

B

`V^(4+)`

C

`Mn^(2+)`

D

`Fe^(3+)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Ti^(4+)=(22-4=18)=[Ar]3d^(0)`
`V^(4+)=(23-4=19)=[Ar]3d^(1)`
`Mn^(2+)=(35-2=23)=[Ar]3d^(5)`
`Fe^(3+)=(26-3=23)=[Ar]3d^(5)`
Hence , it is colourless in nature so , `Ti^(4+)` is not having any unpaired electron.
