प्रश्न

Write the reactions of F2 and Cl2 with water.

उत्तर १

1) `Cl_2 + H_2O     ->                          HCl                    +                          HOCl`

                                     Hydrochloric acid          Hypochlorous acid

2)`2F_(2(g)) + 2H_2O_((l)) -> 4H_(" "(aq))^(+) + 4F_(" "(aq))^(-) + O_(2(g)) + 4HF_((aq))`

उत्तर २

`2F_2(g) + 2H_2O(l) -> 4H^(+)(aq) +4F^(-)(aq) + O_2(g)`

`3F_2(g)+3H_2O(l) ->6H^(+)(aq) + 6F^(-)(aq) + O_3(g)`

`Cl_2(g) + H_2O(l) -> HCl(aq) + HOCl(aq)`

`F_2` oxidisis water , whereas `Cl_2` undergoes disproportion in water

Statement I: Acid strength increases in the order given as HF << HCl << HBr << HI.

Statement II: As the size of the elements F, Cl, Br, and I increase down the group, the bond strength of HF, HCl, HBr, and HI decreases and so the acid strength increases.

In the light of the above statements, choose the correct answer from the options given below.
