Amongst the elements of group 14 the oxidising power of the tetravelent species increases in the orderA. GeltPbltSnB. GeltSnltPbC. PbltGeltSnD. None of the above |

Answer» Correct Answer - B Ge lt Sn lt Pb Oxidation involves decreases in oxidation state of the oxidising agent. Since `Pb^(2+)` is stabler than `Pb^(4+)` while `Ge^(4+)` is stabler than `Ge^(2+)` due to inert pair effect, the oxidising power of the tetravelent species increases in the order Ge lt Sn lt Pb |
