Take CBT

Question

Which of the following is a test for unsaturation that alkynes fail to pass?
Options
A Decolorization of Br2/CCl4
B Decolorization of cold KMnO4
C Reaction with AgNO3/NH3
D Alkynes react with all of these
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Alkynes decolorize Br2 and cold KMnO4 (addition reactions), and terminal alkynes also precipitate with AgNO3/NH3. So they give positive tests.

Hint

Alkynes are unsaturated.
