Coordination number of Al in AICl3 and liquid AICI3
Definition: Coordination number is defined as the number of atoms, ions or molecules that surround a central atom or ion in a crystal or molecule.
Coordination number of Al in AICl3: The formula of AICl3 suggests that each Al atom is surrounded by six Cl atoms. Therefore, the coordination number of Al in AICl3 is 6.
Coordination number of Al in liquid AICI3: In the liquid state, AICI3 exists as a dimer (Al2Cl6). Each Al atom in Al2Cl6 is surrounded by four Cl atoms. Therefore, the coordination number of Al in liquid AICI3 is 4.
Conclusion: The coordination number of Al in crystalline AICl3 and liquid AICI3, respectively, is 6 and 4. Therefore, option C is the correct answer.
