Which one is more soluble in diethyl ether : anhydrous `AlCl_(3)` or hydrated `AlCl_(3)` ? Explain in terms of bonding.

Explanation

To determine which compound is more soluble in diethyl ether—anhydrous AlCl₃ or hydrated AlCl₃—we need to analyze their bonding characteristics and interactions with diethyl ether.

### Step-by-Step Solution:

1. **Understanding the Structures**:
- **Hydrated AlCl₃**: In this form, AlCl₃ is associated with water molecules. It can be represented as Al(H₂O)₆Cl₃. The aluminum ion is coordinated with six water molecules, forming a complex. This hydration stabilizes the aluminum ion through strong hydrogen bonding and ionic interactions.
- **Anhydrous AlCl₃**: This form does not have water molecules associated with it. It exists as a dimer (Al₂Cl₆) in the solid state and has vacant d-orbitals available for bonding.
