Organic Chemistry- Geometric and Structural Isomers of C6H12

Click For Summary

Discussion Overview

The discussion revolves around identifying and naming all structural isomers of hydrocarbons with the formula C6H12, specifically focusing on cyclohexane and its derivatives. The context is a grade 11 chemistry assignment, seeking basic information on isomers.

Discussion Character

  • Homework-related
  • Debate/contested
  • Exploratory

Main Points Raised

  • One participant lists several isomers of C6H12, including cyclohexane, methylcyclopentane, and various substituted cyclobutanes and alkenes.
  • Another participant points out that "1-ethyl-(1/2)methylcyclobutane" is incorrectly included as it contains 7 carbon atoms, suggesting a possible misunderstanding of the isomer count.
  • A third participant challenges the validity of the initial list, accusing another of merely copying from an external source without providing original work.
  • There is a suggestion that more isomers could be derived from pentene, indicating ongoing exploration of the topic.
  • One participant acknowledges the correction regarding the isomer count and proposes that the term "substituted cyclopropane" may have been intended instead.

Areas of Agreement / Disagreement

Participants do not reach consensus on the complete and accurate list of isomers. Disagreement exists regarding the validity of certain isomers and the completeness of the initial attempts.

Contextual Notes

Some participants express uncertainty about the accuracy of the isomer names and the total count, indicating that assumptions about structural validity may not be fully resolved.

Homework Statement



Draw and name all of the structural isomers of hydrocarbons with the formula C6H12 (cyclohexane).

2. Relevant information

This is "only" a grade 11 Chemistry Assignment, therefore I only really need the basics when it comes to isomers- not some of the more complex stuff which you may find in a university course. I would appreciate if you could list the isomers for me, or just give me a number of how many there are.

The Attempt at a Solution



The following are all isomers of Cyclohexane:

[cyclohexane]
[methylcyclopentane]
[ethylcyclobutane]
[1,(1/2/3) dimethylcyclobutane]
[propylcyclo propane]
[1-ethyl-(1/2)methylcyclobutane]
[trimethylcyclopropane]
[hexa-(1/2/3)-ene]
[(2/3/4)-methylpenta-1-ene]
[2,3 dimethylbuta-2-ene]

[(2/3/4)-methylpenta-1-ene]
[2,3 dimethylbuta-2-ene]

Of all the above stated isomers,
1-ethyl-(1/2)methylcyclobutane is not an isomer of C_6H_{12}, as it contains 7 carbon atoms.

Few more isomers would be possible with, pentene.. like (2/3/4)methyl penta-2-ene.

Your attempt at solution is not an attempt at all, you have just copied and pasted these listed at http://wiki.answers.com/Q/What_is_C6H12.

Try to draw them with a pencil and piece of paper.

Good catch, they probably meant substituted cyclopropane.
 
Thank You, now back to MarquisDM..
