(a) What inspired N.Bartlett for carrying out reaction between Xe and `PtF_(6)` ? (b) Arrange the following in the order of property indicated against each set : (i) `F_(2), I_(2), Br_(2), CI_(2)` (increasing bond dissociation enthalpy) (ii) `NH_(3), AsH_(3), SbH_(3), BiH_(3), PH_(3)` (decreasing base strength) (c) Complete the following equations : (i) `CI_(2) + NaOH ("cold and dilute") to` (ii) `Fe^(3+) SO_(2) + H_(2)O to` |

Answer» (a) N.Barlett first prepared a red compound `O_(2) ""^(+)PtF_(6)^(-)`. He then realised that the first ionisation enthalpy of molecular oxygen was almost identical with Xenon. So, he carried out reaction between `Xe " and " PtF_(6)`. (ii) (i) `I_(2) lt F_(2) lt Br_(2) lt CI_(2)` (ii) `NH_(3) gt PH_(3) gt AsH_(3) gt SbH_(3) gt BiH_(3)` (c) (i) `2NaOH + CI_(2) to NaCI + NaOCI + H_(2)O` (ii) `2Fe^(3+) + SO_(2) + 2H_(2)O to 2Fe^(2+) + SO_(4)^(2+) + 4H^(+)` |
