Vedclass · Answer

(C) The reaction $M + O_2 	o MO_2$ represents the formation of a superoxide.Alkali metals react with oxygen to form different oxides depending on their size.$Li$ forms the oxide $Li_2O$,$Na$ forms the peroxide $Na_2O_2$,while heavier alkali metals like $K$,$Rb$,and $Cs$ form superoxides of the type $MO_2$.Therefore,for the reaction $M + O_2 	o MO_2$,the metal $M$ is $K$.Hence,option $C$ is correct.

In the reaction $M + O_2 \to MO_2$ (superoxide),the metal $M$ is
