Production and Uses of 2-Hexyne: Which Image Shows 2 Hexyne

-hexyne is an alkyne, a hydrocarbon with a carbon-carbon triple bond. It is a colorless liquid with a characteristic odor. 2-hexyne is produced industrially by the dehydrogenation of n-hexane or by the acetylene-allene cycloaddition reaction. In the laboratory, it can be prepared by the reaction of 1-bromohexane with sodium acetylide.
-hexyne is used as a starting material for the synthesis of other organic compounds, such as hexanoic acid and hexanal. It is also used as a fuel and as a solvent.

Industrial Production

-hexyne is produced industrially by the dehydrogenation of n-hexane. This process is carried out at high temperatures (500-600 °C) in the presence of a catalyst, such as platinum or palladium. The dehydrogenation reaction is endothermic, so it requires a high energy input.

Laboratory Synthesis, Which image shows 2 hexyne

In the laboratory, 2-hexyne can be prepared by the reaction of 1-bromohexane with sodium acetylide. This reaction is carried out in a polar aprotic solvent, such as dimethylformamide (DMF). The sodium acetylide is generated by the reaction of sodium amide with acetylene.

Comparison with Other Alkynes

-Hexyne shares similar structural features with other alkynes, characterized by a carbon-carbon triple bond. However, its position within the molecule differentiates it from other hexyne isomers.

Structural Differences

Compared to 1-hexyne, which has the triple bond at the terminal carbon, and 3-hexyne, where the triple bond is located in the middle of the carbon chain, 2-hexyne has its triple bond between the second and third carbon atoms. This variation in the triple bond’s position influences the molecule’s reactivity and physical properties.

Chemical Reactivity

The presence of the triple bond in 2-hexyne makes it susceptible to electrophilic addition reactions, similar to other alkynes. However, the location of the triple bond affects the regioselectivity of these reactions. Due to the steric hindrance caused by the neighboring methyl group, 2-hexyne exhibits a preference for Markovnikov addition, where the electrophile adds to the carbon with the most hydrogen atoms.
