Which among the following is correct decreasing order of covalent character of ionic bond?

Options

  1. AAlCl ₃> MgCl ₂> NaCl
  2. BAlCl ₃> NaCl > MgCl ₂
  3. CMgCl ₂> MgCl ₂> AlCl ₃
  4. DNaCl > MgCl ₂> AlCl ₃

Correct answer

A. AlCl ₃> MgCl ₂> NaCl

Step-by-step solution

More is the change on cation greater is polarising power and more is the covalent character order of polarizing power Al ⁺³> Mg ⁺²> Na ⁺
