Question:
$[Sc(H_2O)_6 ]^{3+}$ ion is
$[Sc(H_2O)_6 ]^{3+}$ ion is
Updated On: Aug 15, 2022
- colourless and diamagnetic
- coloured and octahedral
- colourless and paramagnetic
- coloured and paramagnetic
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
$[Sc(H_2O)_6 ]^{3+}$,oxidation state of Sc is + 3.
$\because\, Sc^{3+}$ has no unpaired electrons.
$\therefore [Sc(H_2O)_6]^{3+}$ is diamagnetic and colourless.

Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
