how 1-butyne can be distinguished from 2-butyne by simple chemical tests?

Key Difference – 1-Butyne vs 2-Butyne
All simple aliphatic hydrocarbons are broadly categorized into three types based on the presence of carbon-carbon single or multiple bonds: alkanes, alkenes, and alkynes. Alkanes are saturated hydrocarbons and contain only single carbon-carbon bonds. The general formula of alkane is CnH2n+2. Some common alkanes include methane, ethane, propane, and butane. Alkenes are the unbranched unsaturated hydrocarbons with at least one carbon-carbon double bond. The general formula of alkene is CnH2n. The simplest alkene is ethylene. Butene, hexene, propene are some common examples for alkenes. Alkynes are the unsaturated hydrocarbons with at least one carbon-carbon triple bond. The general formula of alkyne is CnH2n-2. 1-butyne and 2-butyne are two simple alkynes that contain one carbon-carbon triple bond in different places. Both has the same molecular formula of C4H6, but have some differences. The key difference between 1-butyne and 2-butyne is that in 1-butyene, the triple bond is found between first and second carbon, whereas in 2-butyene, it is found between second and third carbon atoms. Because of this difference, these two substances have entirely different characteristic features
