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