Q 2712045839.    

Assertion : Compounds of `Hg^(2+)` ions having an ionic radius of `116` pm are more covalent in character than those of `Ca^(2+)` ions with almost identical size (`114` pm) and the same charge.

Reason : For two ions of the same size and charge, one with an `(n -1 )d^( 10) ns^0` , electronic configuration will be more polarizing than a cation with an `(n- 1 )s^2 (n- 1 )p^6 ns^0` , electronic configuration.

A Both A and R individually true and R is the correct explanation of A
B Both A and R are individually true but R is not the correct explanation of A
C A is true but R is false
D A is false but R is true
