$C_2H_4$

Vedclass · Answer

(C) $C_2H_4$ (ethene) is an alkene. Alkenes react with $KMnO_4$ (Baeyer's reagent) to undergo oxidation,resulting in the decolorization of the purple solution. However,they do not react with ammoniacal $AgNO_3$ (Tollens' reagent) because they lack acidic terminal hydrogen atoms. Terminal alkynes like $C_2H_2$ react with both $KMnO_4$ and ammoniacal $AgNO_3$. Alkanes like $CH_4$ and $C_2H_6$ are saturated hydrocarbons and do not react with either reagent.

Which of the following reacts with $KMnO_4$ but does not react with $AgNO_3$?
