Question

Among licl becl2 mgcl2 and rbcl the compound with greatest and least ionic character respectively

Answer 1

Answer:

Explanation:Compounds having the greatest ionic character-RbCl

Least ionic character-BeCl2

as we know that on going along the period the electronegativity increases and on going down the group electronegativit decreases.  The aninoinc part here is same,therefore the cation having more electronegativity have more covalent character.

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

Answer 2

hi mate.

least ionic character is Becl2.

as we move along the period electronegativity increases .

Electronegativity order is Rbcl<licl<Mgcl2<Becl2.

electronegativity is directly proportional to ionic character.

hope it helps u
