$AlCl_3$

Vedclass · Answer

(C) According to Fajan's rule,the polarizing power of $Al^{3+}$ is high,which leads to significant covalent character in its bonds with less electronegative anions like $Cl^-$.$AlCl_3$ exhibits covalent character in the anhydrous solid state due to the small electronegativity difference between $Al$ and $Cl$ and the high charge density of $Al^{3+}$.In contrast,$Al_2O_3$,$AlF_3$,and $Al_2(SO_4)_3$ are predominantly ionic compounds.
