Discussion Overview

The discussion revolves around the chemical reaction between carbon tetrabromide (CBr4) and 1-butene (CH3-CH2-CH=CH2) in the presence of peroxides. Participants explore the potential products of this reaction, the role of radicals, and the implications of using peroxides.

Discussion Character

  • Exploratory
  • Debate/contested
  • Homework-related
  • Technical explanation

Main Points Raised

  • One participant questions whether bromine (Br) attaches to the methyl group or to the carbon adjacent to it, suggesting possible products like CH2Br-cyclopentane or 1-bromo-1-methylcyclopentane.
  • Another participant speculates whether Br could replace the methyl group entirely.
  • A later post humorously suggests that the reaction could lead to an explosive outcome, indicating uncertainty about the safety and stability of the reaction.
  • One participant emphasizes the need to specify which peroxide is being referred to, hinting at the complexity of the reaction and the possibility of polymerization.
  • Another participant mentions that the presence of radicals could lead to the formation of larger radical species and potentially plastic, though this is presented with a humorous tone.

Areas of Agreement / Disagreement

Participants express various hypotheses about the reaction products and mechanisms, but there is no consensus on the specific outcomes or the nature of the reaction. The discussion remains unresolved with multiple competing views and uncertainties.

Contextual Notes

Participants have not specified the exact peroxide being discussed, which may affect the reaction pathway and products. The discussion also includes humorous elements that may obscure serious technical considerations.

what happens when you add CBr4 to 1-butene (CH3-CH2-CH=CH2) with the presense of peroxides??
 
Physics news on Phys.org
just wondering

:confused: does the Br attach to the methyl group making it CH2Br-cyclopenane?
or does it attach to the carbon that is attached the the methyl group making it 1-bromo-1-methylcyclopentane?
 
or

or would Br replace the methyl group?
 
We have a homework forum for these kinds of questions, I'll move it there.

The peroxide breaks into radicals, radicals attack the butene, the butene turns into a radical, butene joins onto other butenes turning them into radicals, plastic is made. The CBr4 cries because his friends started without him.
Either that or the reaction gets out of control and it explodes. You're talking about mixing peroxides with alkenes; it sounds explosive.
 
answer

so, if it explodes, no reaction occurs?
 
again, specify the reagents. Which peroxide exactly are you referring to? We're probably looking at a polymerization reaction here.
