1.	What is the difference between 2-butyne and 1-butyne ? By which test we can distinguish between these two ?
Answer» SOLUTION :(a) 1-butyne and 2-butyne `(C_(4)H_(6))` are POSITION isomers of each other. `underset("1-butyne")(CH_(3)CH_(2)-C-=CH)""underset("2-butyne")(CH_(3)C-=C CH_(3))` (b) In 1-butyne have acidic HYDROGEN which ATTACH with carbon having triple bond. So it react with `NaNH_(2), AgNO_(3)//(NH_(4)OH)` and `CuSO_(4)//(NH_(4)OH)`, while in 2-butyne acidic hydrogen is absent so it does not give such acidic reaction of hydrogen.
