Aluminium chloride in acidified aqueous solution forms an ion having geometry:
A
Square planar
B
Tetrahedral
C
Octahedral
D
Trigonal bipyramidal
Answer
Octahedral
Explanation
Solution
Determine the Complex Ion Formed: In acidified aqueous solution, AlCl3 forms a complex ion, typically [Al(H2O)6]3+.
Analyze Geometry: - This complex ion has six ligands (water molecules) coordinated around the central aluminum ion. - Six ligands around a central atom generally form an octahedral geometry.
Conclusion: The geometry of [Al(H2O)6]3+ is octahedral.
