What is the Difference Between 1-Butyne and 2-Butyne?
🆚 Go to Comparative Table 🆚The difference between 1-butyne and 2-butyne lies in the position of the double bond in each molecule.
1-butyne, also known as but-1-yne or ethylacetylene, has a chemical formula of C4H6. In this compound, the double bond is located between the first and second carbon atoms.
2-butyne, also known as but-2-yne or dimethylacetylene, also has a chemical formula of C4H6. However, in this case, the double bond is located between the second and third carbon atoms.
Both 1-butyne and 2-butyne are alkenes, which are unsaturated hydrocarbons containing at least one carbon-carbon double bond. The lack of free rotation around carbon-carbon double bonds in alkenes makes their carbon chains less flexible and more rigid than those of alkanes with the same number of carbon atoms.
Comparative Table: 1-Butyne vs 2-Butyne
The main difference between 1-butyne and 2-butyne lies in the position of the triple bond within the molecule. Here is a comparison table highlighting the differences between the two:
Property | 1-Butyne | 2-Butyne |
---|---|---|
Terminal/Non-terminal Alkyne | Terminal | Non-terminal |
Position of Triple Bond | Connects C1 and C2 | Connects C2 and C3 |
Physical State | Colorless gas | Colorless liquid |
Chemical Reactivity | Reacts with ammoniacal AgNO3 solution, forming a white precipitate (silver 1-butynide) | Does not react with ammoniacal AgNO3 solution |
Chemical Reactivity | Reacts with ammoniacal CuCl2 solution, forming a red precipitate (copper 1-butynide) | Does not react with ammoniacal CuCl2 solution |
Both 1-butyne and 2-butyne have the same chemical formula, C4H6, but their different molecular structures result in distinct chemical and physical properties.
