Question

Which of the following has the highest ionic character? (A) MgCl2 (B) CaCl2 (C) BaCl2 (D) BeCl2

Tardigrade Admin · Accepted Answer

Of all alkaline earth metal ions, Ba2+ is the largest. Since the anion is the same with all the four, according to Fajans’ rule, BaCl2 will have the highest ionic character.

Q. Which of the following has the highest ionic character?

$M g C l_{2}$

$C a C l_{2}$

$B a C l_{2}$

$B e C l_{2}$

Of all alkaline earth metal ions, $B a^{2 +}$ is the largest. Since the anion is the same with all the four, according to Fajans’ rule, $B a C l_{2}$ will have the highest ionic character.
