Butyne-1 and butyne- 2 can be distinguished by

Options

  1. AH ₂ SO ₄
  2. BAgNO ₃+ NH ₄ OH
  3. CK ₂ Cr ₂ O ₇
  4. DNH ₄ OH

Correct answer

B. AgNO ₃+ NH ₄ OH

Step-by-step solution

Butyne-1 has the terminal hydrogen atom which reacts with ammonical silver nitrate easily and liberate hydrogen. 2 CH ₃ CH ₂ C CH + Ag ₂ O white ppt CH ₃ CH ₂ C CAg + H ₂ O Hence butyne- 1 and butyne- 2 are distinguished by AgNO ₃+ NH ₄ OH
