Vedclass · Answer

(A) Baeyer's test (alkaline $KMnO_4$) is given by both alkenes and alkynes,resulting in the decolorization of the purple solution.Ammoniacal silver nitrate (Tollens' reagent) gives a white precipitate only with terminal alkynes (alkynes with an acidic hydrogen).$C_2H_4$ (ethene) is an alkene,so it gives a positive Baeyer's test but does not react with Tollens' reagent.$C_3H_4$ (propyne) and $C_2H_2$ (ethyne) are terminal alkynes,so they give positive results for both tests.$C_2H_6$ (ethane) is an alkane and does not give either test.

Which of the following compounds gives a positive Baeyer's test but does not form a white precipitate with ammoniacal silver nitrate solution?
