1 butyne and 2-butyne are different from each other on the basis of triple bond.
They are distinguished by Tollen's reagent test.
It is used to determine presence of aldehyde and aromatic aldehyde etc.
It consist of silver nitrate and ammonia.
Acidic hydrogen is present in 1 butyne
Acidic hydrogen is absent in 2 butyne
