Q33 Which of the following laboratory tests can be performed for terminal alkynes
Answers
Answer:
The reaction with Tollens reagent can be performed as laboratory tests for terminal alkynes.
Explanation:
A white precipitate of silver salt is formed when terminal alkynes react with Tollen's reagent (ammoniacal solution of silver nitrate).
Tollen's reagent is prepared by adding a dilute solution of ammonium hydroxide to silver nitrate solution till the dirty white precipitate of AgOH first formed gets dissolved.
The reaction is shown below.
R-C≡CH + [Ag(NH₃)₂]⁺ → R-C≡C-Ag + NH₄⁺ + NH₃
Internal alkynes do not give this reaction.
ANSWER:
The response with Tollens reagent can be proceeded as research facility tests for terminal alkynes.
EXPLANATION:
A white hasten of silver salt is framed when terminal alkynes respond with Tollen's reagent ammonical arrangement of silver nitrate.
The response is displayed beneath.
R-C≡CH + [Ag(NH₃)₂]⁺ → R-C≡C-Ag + NH₄⁺ + NH₃
Tollen's reagent is ready by adding a weaken arrangement of ammonium hydroxide to silver nitrate arrangement till the grimy white encourage of AgOH originally framed gets disintegrated.
Inside alkynes don't give this response.
