Vedclass · Answer

(A) $1$-Alkynes (terminal alkynes) contain an acidic hydrogen atom attached to the $sp$-hybridized carbon $(R-C \equiv C-H)$.When treated with Tollen's reagent (ammoniacal silver nitrate,$AgNO_3 + NH_4OH$),terminal alkynes form a white precipitate of silver acetylide $(R-C \equiv C-Ag)$.$2$-Alkynes (internal alkynes) do not have an acidic hydrogen atom and therefore do not react with Tollen's reagent to form a precipitate.Thus,Tollen's reagent is used to distinguish between $1$-alkyne and $2$-alkyne.
