The correct order of the increasing ionic character is

A

BeCl₂ < MgCl₂ < CaCl₂ < BaCl₂

B

BeCl₂ < MgCl₂ < BaCl₂ > CaCl₂

C

BeCl₂ < BaCl₂ < MgCl₂ < CaCl₂

D

BaCl₂ < CaCl₂ < MgCl₂ < BeCl₂

Correct Answer

Option A

Detailed Explanation

Cl is common in all the given molecules. As we go down in a group, electro-negativity decreases and tendency to form ionic compound increases. Hence, tendency to lose electrons also increases. The order of increasing ionic character is : BeCl₂ < MgCl₂ < CaCl₂ < BaCl₂.
