When C ₂ H ₂, CH ₄ and C ₂ H ₄ pass through a test tube which has ammonical Cu ₂ Cl ₂ , find out which gas comes out unaffected from test tube?

Options

  1. AC ₂ H ₂ and CH ₄
  2. BC ₂ H ₂ and C ₂ H ₄
  3. CC ₂ H ₄ and CH ₄
  4. DC ₂ H ₂

Correct answer

C. C ₂ H ₄ and CH ₄

Step-by-step solution

C ₂ H ₂ forms copper acetylide with ammonical Cu ₂ Cl ₂ array l Cu ₂ Cl ₂+2 NH ₄ OH Cu ₂ O + H ₂ O +2 NH ₄ Cl Cu ₂ O + C ₂ H ₂ (copper acetylide) Cu ₂ C ₂ + H ₂ O array
