[Sc(H(2)O)(6)]^(3+) ion is...

`[Sc(H_(2)O)_(6)]^(3+)` ion is

A

Colourless and diamagnetic

B

Coloured and octahedral

C

Colourless and paramahnetic

D

coloured and paramagnetic

Text Solution

Verified by Experts

The correct Answer is:
A
`"In" [Sc(H_(2)O)_(6)]^(3+), ` oxidation state of SC is `+3`

`therefore Sc^(3+)` has no unpaired electron .
` therefore [Sc (H_(2)O)_(6)]^(3+)` is diamagnetic and colourless .
