Order of polarising power of Be2+>Mg2+>Ca2+>Ba2+ Thus, ionic nature is of following order BaCl2

Q. The correct order of increasing ionic character is

$B e C l_{2} < M g C l_{2} < C a C l_{2} < B a C l_{2}$

$B e C l_{2} < C a C l_{2} < M g C l_{2} < B a C l_{2}$

$M g C l_{2} < C a C l_{2} < B e C l_{2} < B a C l_{2}$

$B a C l_{2} < C a C l_{2} < M g C l_{2} < B e C l_{2}$

Order of polarising power of $B e^{2 +} > M g^{2 +} > C a^{2 +} > B a^{2 +}$ Thus, ionic nature is of following order $B a C l_{2} < M g C l_{2} < C a C l_{2} < B a C l_{2}$

Q. The correct order of increasing ionic character is

BeCl2​<MgCl2​<CaCl2​<BaCl2​

BeCl2​<CaCl2​<MgCl2​<BaCl2​

MgCl2​<CaCl2​<BeCl2​<BaCl2​

BaCl2​<CaCl2​<MgCl2​<BeCl2​

Order of polarising power of Be2+>Mg2+>Ca2+>Ba2+ Thus, ionic nature is of following order BaCl2​<MgCl2​<CaCl2​<BaCl2​

$B e C l_{2} < M g C l_{2} < C a C l_{2} < B a C l_{2}$

$B e C l_{2} < C a C l_{2} < M g C l_{2} < B a C l_{2}$

$M g C l_{2} < C a C l_{2} < B e C l_{2} < B a C l_{2}$

$B a C l_{2} < C a C l_{2} < M g C l_{2} < B e C l_{2}$

Order of polarising power of $B e^{2 +} > M g^{2 +} > C a^{2 +} > B a^{2 +}$ Thus, ionic nature is of following order $B a C l_{2} < M g C l_{2} < C a C l_{2} < B a C l_{2}$
