Vedclass · Answer

(C) comproportionation reaction is a type of redox reaction where two reactants,each containing an element in a different oxidation state,form a product in which the element is in an intermediate oxidation state.$1$. $H_2S (-2) + SO_2 (+4) 	o S (0) + H_2O$: This is a comproportionation reaction.$2$. $I^{-} (-1) + IO_3^{-} (+5) + H^{+} 	o I_2 (0) + H_2O$: This is a comproportionation reaction.$3$. $K_2MnO_4 (+6) + H^{+} 	o KMnO_4 (+7) + MnO_2 (+4)$: This is a disproportionation reaction,where a single reactant in an intermediate oxidation state forms products with higher and lower oxidation states.$4$. $MnO_4^{-} (+7) + Mn^{2+} (+2) 	o MnO_2 (+4)$: This is a comproportionation reaction.Therefore,the reaction in option $C$ is a disproportionation reaction,not a comproportionation reaction.
