SUMMARY

The discussion centers on the necessity of using an organic solvent for the substitution reaction between bromine and hexane. Participants highlight that while bromine is a liquid, its reactivity is enhanced in an organic solvent due to the solubility of bromine radicals. Without an organic solvent, the reaction may not occur effectively, as the bromine radicals could remain insoluble in bromine, hindering the reaction process.

PREREQUISITES
  • Understanding of substitution reactions in organic chemistry
  • Knowledge of radical mechanisms in chemical reactions
  • Familiarity with solubility principles in organic solvents
  • Basic concepts of homolysis and radical formation
NEXT STEPS
  • Research the role of solvents in radical substitution reactions
  • Study the mechanisms of bromination in organic chemistry
  • Explore the solubility of halogens in various organic solvents
  • Learn about the effects of solvent polarity on reaction rates
USEFUL FOR

Chemistry students, organic chemists, and researchers interested in reaction mechanisms and solvent effects in substitution reactions.

In substitution reaction between bromine and hexane, why the bromine should be in organic solvent? Bromine is already a liquid!

Good question. Maybe its because the homolysis can only take place in a solvent. Maybe the Br radicals are insoluble in Br2.
 
I just can't understand :(
Hexane can dissolve bromine.What would happen if we don't add Br into the organic solvent?
There will be no reaction?Or sth bad will happen?
