Vedclass · Answer

(D) The reaction between sodium thiosulphate $(Na_2S_2O_3)$ and iodine $(I_2)$ is given by: $2Na_2S_2O_3 + I_2 \rightarrow Na_2S_4O_6 + 2NaI$ In this reaction,sodium thiosulphate is oxidised to sodium tetrathionate $(Na_2S_4O_6)$. Therefore,option $A$ is correct. Sodium thiosulphate is highly soluble in water,so option $B$ is correct. Ozone reacts with alkenes to form ozonides,which is a standard test for unsaturation,so option $C$ is correct. Option $D$ states that sodium thiosulphate reacts with iodine to form sodium sulphate,which is incorrect as it forms sodium tetrathionate.

Column-$I$ [Type of reaction]	Column-$II$ [Example]
$I$. Intermolecular redox reaction	$A$. $CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O$
$II$. Intramolecular redox reaction	$B$. $NH_4NO_2 \rightarrow N_2 + 2H_2O$
$III$. Disproportionation reaction	$C$. $2H_2O_2 \rightarrow 2H_2O + O_2$
$IV$. Comproportionation reaction	$D$. $KClO_3 \rightarrow KCl + \frac{3}{2}O_2$
