Organic Chemistry - Polymerization of Propene to Polypropylene

Click For Summary

Discussion Overview

The discussion revolves around the polymerization of propene to polypropylene, specifically focusing on the radical mechanism involved in the propagation step of the reaction mechanism diagram. Participants are seeking validation of their answers related to a homework assignment.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant requests feedback on their answer regarding the propagation step of the polymerization mechanism.
  • Another participant confirms that the initial answer appears correct but suggests that a rejection may stem from a potential issue with the definition of 'propagation'.
  • A participant expresses concern after their answer was rejected by the online homework system and questions whether they overlooked something.
  • Another participant inquires if the homework program provided a correct answer after multiple attempts and suggests sharing the answer with a professor for further clarification.
  • A participant notes that the program does not provide the correct answer, possibly due to settings controlled by the course administrator, and plans to consult their professor.

Areas of Agreement / Disagreement

Participants generally agree on the correctness of the initial answer, but there is uncertainty regarding the homework system's rejection and the lack of feedback from the program.

Contextual Notes

There are limitations related to the online homework system's functionality, including the potential disabling of answer feedback by the course administrator, which may affect participants' ability to verify their responses.

Homework Statement



The polymerization of propene to polypropylene progresses through a radical mechanism.

Complete the propagation step of the reaction mechanism diagram by drawing in the missing lone pairs, radical electrons, atomic charges, and electron-flow arrows where appropriate.

You have it right. If it is not accepted then there may be an issue with the definition of 'propagation'. Post back once you have submitted the answer.
 
Hmm, the online homework thing rejected my answer. Since I used up all my tries I can't submit any more answers. I hope I'm not missing anything in my answer.
 
Sorry to hear about it. Didn't it give you the answer? Usually the program gives you the answer after your have exhausted your chances.
Do you want to share what else you tried?
Also, you may want to send this answer to your professor and ask him for a correct response.
 
For some reason, the program does not give me the correct answer probably because the course administrator has turned that function off. I'll send my answer to my professor and see what he says.
