Ethane and ethene

Vedclass · Answer

(A) Ethyne $(C_2H_2)$ contains acidic hydrogen atoms attached to $sp$-hybridized carbon atoms. It reacts with ammoniacal $AgNO_3$ (Tollens' reagent) to form a white precipitate of silver acetylide $(Ag-C \equiv C-Ag)$. Ethane $(C_2H_6)$ and ethene $(C_2H_4)$ do not contain acidic hydrogen atoms and therefore do not react with ammoniacal $AgNO_3$. Thus,ethane and ethene remain unreacted.

$A$ mixture of ethane,ethene,and ethyne is passed through ammoniacal $AgNO_3$ solution. The gases which remain unreacted are
