How would you account for the following : (i) H_(2)S is more 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 fluorine.

The enthalpy changes at 25^(@)C in successive breaking of O - H bonds of water are : H_(2)O(g) rarr H(g) + OH(g) Delta H = 498 kJ mol^(-1) OH(g) rarr H(g) + O(g) Delta H = 428 kJ mol^(-1) The bond enthalpy of the O-H bond is :
