(C) The reactions are as follows:$(A)$ $2F_2 + 4NaOH 	ext{ (hot, conc.)} \longrightarrow 4NaF + O_2 + 2H_2O$ (Forms $O_2$)$(B)$ $2F_2 + 2H_2O \longrightarrow 4HF + O_2$ (Forms $O_2$)$(C)$ $Cl_2 + 2NaOH 	ext{ (cold, dil.)} \longrightarrow NaCl + NaClO + H_2O$ (Does not form $O_2$)$(D)$ $CaOCl_2 + H_2SO_4 	ext{ (dil.)} \longrightarrow CaSO_4 + H_2O + Cl_2$ (Does not form $O_2$ directly,but the question asks for the pair that does not form oxygen. Note: $CaOCl_2$ is bleaching powder. The reaction with dilute acid releases $Cl_2$. However,option $C$ is the standard textbook example for the reaction of $Cl_2$ with cold dilute $NaOH$ which produces hypochlorite,not oxygen.)Comparing the options,$Cl_2$ with cold dilute $NaOH$ is the classic reaction that produces hypochlorite $(ClO^-)$ and chloride $(Cl^-)$,not oxygen.

Which one of the following pairs of reactants does not form oxygen when they react with each other?
