With which 2 of these 5 chemicals would Chlorine not react? N, NaOH, O2, NaBr, Fe
$\ce{NaOH}$


$$\ce{2NaOH + Cl2 → NaCl + NaClO + H2O}$$


  Reaction between chlorine and sodium hydroxide to form sodium
  chloride, sodium hypochlorite and water. The reaction takes place in a
  cold dilute solution. (Chemiday 1)


$$\ce{3Cl2 + 6NaOH → NaClO3 + 5NaCl + 3H2O}$$


  Reaction interaction chlorine and sodium hydroxide to form sodium
  chlorate, sodium chloride and water. The reaction proceeds in a
  concentrated solution with heating.(chemiday 2)



$\ce{NaBr}$


$$\ce{2NaBr + Cl2 → 2NaCl + Br2}$$


  Reaction between sodium bromide and chlorine to form bromine chloride
  and sodium. Hot - sodium bromide. The industrial method of producing
  bromine.(chemiday 3)



$\ce{Fe}$


$$\ce{2Fe + 3Cl2 -&gt;[\Delta] 2FeCl3}$$


  The reaction of chlorine and ferric chloride reaction with the
  formation of iron (III). The reaction proceeds at a temperature above
  250 C °.(chemiday 4)


But I couldn't find any reaction of chlorine with neither nitrogen or oxygen. Guess what, chlorine doesn't have sufficient energy to break the triple bond of nitrogen or double bond of oxygen.
