How would you account for the following : (i) `H_(2)S` is acidic than`H_(2)O`. (ii) The N-O bond in `NO_(2)^(-)` is shorter than the `N-O` bond in `NO_(3)^(-)`. (iii) Both `O_(2)` and `F_(2)` stabilize high oxidation states but the ability of oxygen to stabilize the higher oxidation state exceeds that of flurine. |

Answer» (i)Size of centre atom is `H_(2)S` is larege than `H_(2)O` Hence the S-H bond is weaker than O-H bond. Hence `H_(2)S` can dissociate to given `H+`ions (iii)` O_(2)` exceeds `F_(2)` in doing so due to ability of oxygn to from multiple bonds with metals. |
