Question

The charge/size ratio of a cation determines its polarizing power. Which one of the following sequences represents the increasing order of the polarizinig order of the polarizing power of the cationic species, K+, Ca2+, Mg2+, Be2+? (A) Mg2+ ,Be2+ ,K+ ,Ca2+ (B) Be2+ ,K+ ,Ca2+ ,Mg2+ (C) K+ ,Ca2+ ,Mg2+ ,Be2+ (D) Ca2+ ,Mg2+ ,Be2+ ,K+

Higher the charge/size ratio, more is the polarizing power. ∴ K+ ,Ca2+ ,Mg2+ ,Be2+

Q. The charge/size ratio of a cation determines its polarizing power. Which one of the following sequences represents the increasing order of the polarizinig order of the polarizing power of the cationic species, $K^{+}, C a^{2 +}, M g^{2 +}, B e^{2 +}$ ?

$M g^{2 +}, B e^{2 +}, K^{+}, C a^{2 +}$

$B e^{2 +}, K^{+}, C a^{2 +}, M g^{2 +}$

$K^{+}, C a^{2 +}, M g^{2 +}, B e^{2 +}$

$C a^{2 +}, M g^{2 +}, B e^{2 +}, K^{+}$

Higher the charge/size ratio, more is the polarizing power.
$∴ K^{+}, C a^{2 +}, M g^{2 +}, B e^{2 +}$
