AlCl3 is covalent while AlF3 is ionic.
Flexi Says: Yes, AlCl3, or aluminum chloride, is a binary ionic compound. It is composed of two different elements: aluminum (Al) and chlorine (Cl). Was this helpful?
The Al3+ cation has a 3+ charge which allows it to distort the Cl- ion more. This means more electrons are drawn away from the Cl-ion. This means now that there is more sharing of the electrons giving AlCl3 more covalent character. The small Na+ Ion and the Cl- ion is not as distorted as much as the Cl- ion in AlCl3.
Therefore CaCl2 is not a covalent bond but an ionic bond.
Lithium chloride is an ionic compound but it also has some covalent character due to the very small size of lithium metal. The covalent character in ionic compounds is determined by using Fajan's rule.
Aluminum chloride forms a covalent bond because the electronegativity difference between \[Al\] and \[Cl\] is small. Tendency of aluminum (less electropositive) to lose an electron to form cation and chlorine (less electronegative) to accept an electron to form anion is less in this case.
Aluminium chloride, also known as aluminium trichloride, is an inorganic compound with the formula AlCl 3. It forms a hexahydrate with the formula [Al(H 2O) 6]Cl 3, containing six water molecules of hydration.
Answer: ionic
Therefore, the bond is largely classified as an ionic bond composed of iron (II) cation and chloride anions.
Aluminum chloride is a neutral ionic compound, which is composed of aluminum and chlorine ions.
It is a covalent compound because the the electronegativity difference between sulfur and chlorine is only 0.5.
