Which one of the following pairs of reactants does not form oxygen when they react with each other?
Options
- AF ₂, NaOH solution (hot, conc.)
- BF ₂, H ₂ O
- CCl ₂, NaOH solution (cold, dilute)
- DCaOCl ₂, H ₂ SO ₄ (dilute, small amount)
Correct answer
C. Cl ₂, NaOH solution (cold, dilute)
Step-by-step solution
Cl ₂+ cold, dil 2 NaOH NaCl + NaClO + H ₂ O Chlorine react with cold and dilute NaOH to give sodium hypochlorite.
