Ethylene

Vedclass · Answer

(C) The hydrocarbon is Ethylene $(CH_2=CH_2)$.$1$. Sabatier and Senderen's reaction involves the catalytic hydrogenation of unsaturated hydrocarbons using $Ni$ catalyst at $300\ ^oC$. Ethylene undergoes this reaction: $CH_2=CH_2 + H_2 \xrightarrow[300\ ^oC]{Ni} CH_3-CH_3$.$2$. Ammoniacal silver nitrate (Tollens' reagent) reacts only with terminal alkynes (having acidic hydrogen) to form a white precipitate. Ethylene does not contain acidic hydrogen,so it does not form a precipitate.

$A$ hydrocarbon containing $2$ carbon atoms gives Sabatier and Senderen's reaction but does not give a precipitate with ammoniacal silver nitrate solution. The hydrocarbon is:
