MCQ
Which of the following reagent is used to distinguish propene and propyne
  • A
    $Br_2,\,CCl_4$
  • B
    Dil. $KMnO_4 /$ $O{H^\Theta }$
  • C
    Conc. $H_2SO_4$
  • $AgNO_3$ in $NH_4OH$

Answer

Correct option: D.
$AgNO_3$ in $NH_4OH$
d
Propene and propyne can be distinguish by using Ammoniacal silver nitrate test.

Propyne has an acidic hydrogen due to which it readily react with Ammoniacal silver nitrate gives white precipitate while propene does not give any precipitate.
