Draw the structures of the following : (i) H_(2)S_(2)O_(7)(ii) HClO_(3

1.	Draw the structures of the following : (i) H_(2)S_(2)O_(7)(ii) HClO_(3)(b)Explain the following observations :(i)In the structure ofHNO_(3) the N-Obond(121 pm) is shorter thanthe N-OH bond (140 pm).(ii) All the P- Cl bonds in PCl_(5) are not equivalent.(iii) ICl is more reactive than I_(2) .
Answer» Solution :(a) (i) Structure of`H_(2)S_(2)O_(7)`(OLEUM) (ii)`HClO_(3)`(CHLORIC acid) (b)(i)Dueto DOUBLE bond choracter of N- O bond the length is shorter. (ii)All theP- Cl bonds in `PCl_(5)` are not equivalenet due to the fact that the axial bond pairs suffer more repulsion as compared to equatorial bond pairs. (iii) IClismore reactive than `I_(2)`(EXCEPT `F_(2))` . Because X-X' bond in INTERHALOGENS is weaker than X-X bond in halogens except F-F bonds.Thus , I- Clbondis weaker thanI-I bondSoIClis more reactive than `I_(2)`.
