OK, how can you make alkynes?

 

[AGNuke]

First step would be to combine two units of ethene to form a 4 carbon backbone.

 

[Teemo]

You need to add two more carbons, so consider how you would have the ethene attack a 2 carbon halide while having a triple bond.

There are several methods for converting ethene to but-1-yne. One common method is through a process called dehydrohalogenation, where ethene is reacted with a hydrogen halide, such as hydrogen chloride, to form a halogenated alkene intermediate. This intermediate can then undergo further reactions, such as elimination reactions, to form the desired but-1-yne product. Another method is through a catalytic hydration process, where ethene is reacted with water in the presence of a catalyst to form ethanol, which can then be further reacted to form but-1-yne. Additionally, ethene can also be converted to but-1-yne through oxidative coupling reactions, where two molecules of ethene are reacted to form but-1-yne and other byproducts. It is important to carefully control reaction conditions and select appropriate catalysts in order to achieve high yields of but-1-yne.
