Vedclass · Answer

(D) Terminal alkynes,such as ethyne $(C_2H_2)$,contain acidic hydrogen atoms attached to $sp$-hybridized carbon atoms.These acidic hydrogens can be replaced by active metals like sodium $(Na)$ to form sodium acetylides with the evolution of hydrogen gas $(H_2)$.The reaction is: $2CH \equiv CH + 2Na 	o 2CH \equiv C^{-}Na^{+} + H_2$.
