Select wrong chemical reaction among thefollowing:

Options

  1. A( MnO ₂+4 HCl MnCl ₂+ Cl ₂+2 H ₂ O )
  2. B( 8 NH ₃+3 Cl ₂ 6 NH ₄ Cl + N ₂ )
  3. C( 2 NaOH + Cl ₂ 2 NaCl + H ₂+ O ₂ )
  4. D( 2 Ca (O H)₂+2 Cl ₂ Ca (O C l)₂+ CaCl ₂+2 H ₂ O )

Correct answer

C. ( 2 NaOH + Cl ₂ 2 NaCl + H ₂+ O ₂ )

Step-by-step solution

When ( NaOH ) reacts with ( Cl ₂ ), hydrogen gas does not liberate, therefore, this reaction is wrong reaction. Correct reaction is, ( 2 NaOH + Cl ₂ NaCl + NaClO + H ₂ O )
