$C_2H_2$

Vedclass · Answer

(D) Terminal alkynes,such as ethyne $(C_2H_2)$,contain acidic hydrogen atoms attached to $sp$-hybridized carbon atoms.These acidic hydrogen atoms can be replaced by active metals like sodium $(Na)$ to release hydrogen gas $(H_2)$.The reaction is: $HC \equiv CH + 2Na \rightarrow NaC \equiv CNa + H_2 \uparrow$.Alkanes $(CH_4, C_2H_6)$ and alkenes $(C_2H_4)$ do not have sufficiently acidic hydrogen atoms to react with sodium.

Which of the following compounds produces hydrogen gas upon reaction with sodium?
