Question Asked by a Student from EXXAMM.com Team

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
