SUMMARY

Ethene can be converted to but-1-yne through a series of reactions that involve combining two units of ethene to create a four-carbon backbone. The process requires the addition of two more carbon atoms, which can be achieved by having ethene react with a two-carbon halide while forming a triple bond. This method effectively transforms the alkene into an alkyne, specifically but-1-yne.

PREREQUISITES
  • Understanding of alkene and alkyne structures
  • Knowledge of organic reaction mechanisms
  • Familiarity with halogenation reactions
  • Basic grasp of carbon chain elongation techniques
NEXT STEPS
  • Study the mechanism of alkene to alkyne conversion
  • Research halogenation reactions involving ethene
  • Learn about carbon chain elongation methods in organic chemistry
  • Explore the properties and applications of but-1-yne
USEFUL FOR

Chemistry students, organic chemists, and anyone interested in synthetic pathways for converting alkenes to alkynes.

OK, how can you make alkynes?
 
First step would be to combine two units of ethene to form a 4 carbon backbone.
 
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.
