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 $([Ag(NH_3)_2]OH)$,$1$-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.Thus,Tollen's reagent is used to distinguish between them.
