WebMay 15, 2014 · 1-butyne is a terminal alkyne while 2-butyne is not. Only terminal alkynes and so 1-butyne gives a white precipitate of silver butynide with ammoniacal AgNO3. 2-butyne does not give a white precipitate and hence ammoniacal silver nitrate can be used to distinguish 1–butyne from 2-butyne. This conversation is already closed by Expert WebButyne -1 having acidic hydrogen gives silver acetylide precipitate, butene-1 has no acidic hydrogen ,hence, does not give a precipitate due to absence of acidic hydrogen.

[1] 1-Butyne participates in reactions typical for terminal alkynes, such as alkyne metathesis, [2] hydrogenation, condensation with formaldehyde. Based on its heat of combustion, it is slightly less stable than its isomer 2-butyne.
