Identify the incorrect statement among the following

Options

  1. AOzone reacts with SO ₂ to give SO ₃
  2. BSilicon reacts with NaOH _ (aq) in the presence of air to give Na ₂ SiO ₃ and H ₂ O
  3. CCl ₂ reacts with excess of NH ₃ to give N ₂ and HCl
  4. DBr ₂ reacts with hot and strong NaOH solution to give NaBr , NaBrO ₄ and H ₂ O

Correct answer

D. Br ₂ reacts with hot and strong NaOH solution to give NaBr , NaBrO ₄ and H ₂ O

Step-by-step solution

Br ₂ reacts with hot and strong NaOH to give NaBr , NaBrO ₃ and H ₂ O . Hence, (D) is incorrect statement.
