The charge /size ratio of a cation dermines its polarizing power. Which one of the following sequences represents the increasing order of the polarixing power of the cationic species , `K^+ , Ca^+ , Mg^(2+), Be^(2+)` ?A. ` Mg^(2+) lt Be^(2+) lt K^+ lt Ca^(2+)`B. `Be^(2+) lt K^+ lt Ca^(2+) lt Mg^(2+)`C. `K^+ lt Ca^(2+) lt Mg^(2+) lt Be ^(2+)`D. `Ca^(2+) lt Mg^(2+) lt be^(2+) lt K^(+)` |

Answer» Correct Answer - C Higher the charge`//`size ratio , more is the polarizing power . `:. k^(+) lt Ca^(2+) lt Mg^(2+) lt Be^( 2+)` . |
