Organic Chemistry- Geometric and Structural Isomers of C6H12

AI Thread Summary
The discussion centers on identifying and naming the structural isomers of hydrocarbons with the formula C6H12, specifically cyclohexane. Participants list various isomers, including cyclohexane, methylcyclopentane, and ethylcyclobutane, while noting that 1-ethyl-(1/2)methylcyclobutane is incorrectly included as it has seven carbon atoms. There is an emphasis on the need for basic understanding suitable for a grade 11 chemistry assignment, avoiding complex university-level details. Additionally, some users encourage drawing the isomers rather than relying on copied lists. The conversation highlights the importance of accuracy in identifying isomers for educational purposes.

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..
 
Thread 'Confusion regarding a chemical kinetics problem'
TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
