- $[Al(H_2O)_6]^{3+}, sp^3d^2$
- $[Al(H_2O)_4]^{3+}, sp^3$
- $[Al(H_2O)_4]^{3+}, dsp^2$
- $[Al(H_2O)_6]^{3+}, d^2sp^3$

The Correct Option is A
Solution and Explanation
$AlCl_3$ in acidified aqueous solution form a
$[Al(H_2O)_6]^{3+}$
$Al^{+3} = [Ne]$
$sp^3d^2$
$[Al(H_2O)_6]^{3+}$
$Al^{+3} = [Ne]$
$sp^3d^2$

Concepts Used:
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.
