After Pauling rules the electronegativity of aluminium is 1,61 and the electronegativity of chlorine 3,16; the difference is 1,55.
1.55
1.5 Cl has an electronegativity of 3.0 and Aluminium has an electronegativity of 1.5 3.0-1.5=1.5
Hydrogen chloride (HCl) is polar because Cl has more electronegativity they attract more ionic bond.So,due to the electronegativity difference it is polar.
AlCl3Although a metal-nometal compound, AlCl3 is not ionic (as might be predicted). Single covalent bonds form between aluminum and three chlorine atoms, forming AlCl3 molecules. Two of these join together (forming a 'dimer') with formula Al2Cl6. Aluminium bromide and aluminum iodide are similar in nature. However, aluminum fluoride is ionic. Why the difference in bonding? It all has to do with the difference in electronegativity of the elements:Al & F - difference of 2.37Al & Cl - difference of 1.55Al & Br - difference of 1.35Al & I - difference of 1.05Generally, if the difference in electronegativity is greater than 2.0 then the bond will be ionic. If less than 2.0, then the bond will be covalent.
Aluminum is more electronegative than sodium. The electronegativity of aluminum is 1.61. The electronegativity of sodium is 0.93.
Covalent bonds are formed when the electronegativity difference between the two atoms is less than 1.7. Ionic bond is formed between two atoms having electronegativity difference of 1.7 or above. The electronegativity of hydrogen is 2.1 and that of chlorine is 3.0. So in HCl the electronegativity difference is 3.0-2.1=0.9 which is less than 1.7. Therefore they will form a covalent compound. Electronegativity of Sodium is 0.9 and that of chlorine is 3.0. So the electronegativity difference is 3.0-0.9=2.1 that is greater than 1.7 and will form an ionic bond and hence it will be an ionic bond.
Germanium chloride is a bond between a metal and a nonmetal. The electronegativity difference between these substances is great. Thus, this compound has an ionic bond.
Under IUPAC naming conventions, AlCl3 is called aluminum chloride. It is also commonly called aluminum trichloride and aluminum (III) chloride.
