Ionic character of compounds
Ionic character of a compound can be determined by the difference in electronegativity between the two elements that form the compound. The greater the difference in electronegativity, the greater the ionic character of the compound.
The electronegativity values of Li, Rb, Be, and Mg are 1.0, 0.8, 1.5, and 1.2 respectively.
Greatest and least ionic character
LiCl, RbCl, BeCl2, and MgCl2 are all binary compounds consisting of a metal and a non-metal.
Li and Cl have a difference in electronegativity of 3.0 - 1.0 = 2.0
Rb and Cl have a difference in electronegativity of 3.0 - 0.8 = 2.2
Be and Cl have a difference in electronegativity of 3.0 - 1.5 = 1.5
Mg and Cl have a difference in electronegativity of 3.0 - 1.2 = 1.8
Therefore, RbCl has the greatest ionic character since it has the greatest difference in electronegativity, while BeCl2 has the least ionic character since it has the smallest difference in electronegativity.
Conclusion
The correct option is C, RbCl has the greatest ionic character, while BeCl2 has the least ionic character.

Compounds having the greatest ionic character is RbCl and least ionic character is BeCl2.Explanation:As, we know that on going along the period the electronegativity increases and on going down the group electronegativit decreases.The anioinc part here is same, therefore the cation having more electronegativity have more covalent character.Increasing order of electronegativity order is Rb\Li\Mg\Be.Thus, it can be seen that the percentage of ionic character is directly proportional to the electronegativity of the element.Hence, correct answer is (c).
