# Organic Chemistry- Geometric and Structural Isomers of C6H12

1. The problem statement, all variables and given/known data

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.

3. 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]

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.
