Ethylene and acetylene can be distinguished by using
Options
A Bromine in CCl4
B Tollens' reagent
Correct Answer
C Baeyer's reagent
D Phenylhydrazine
Correct Answer

Option B is the correct answer.

Detailed Explanation

Acetylene (alkyne) gives a precipitate with Tollens' reagent (ammoniacal silver nitrate) due to the acidic terminal alkyne hydrogen. Ethylene (alkene) does not react with Tollens' reagent. Both decolorize bromine and KMnO4.

Which reagent reacts with terminal alkynes but not alkenes?
