Isomers

What are all the possible isomers of Propane?

[Darkblade48]

I'm slightly confused by your question; propane only exists in one conformation...?

1/ this isn't a 'we'll do your homeowrk for you' forum.

2/ pretty obvious it only has one possible layout. try it out draw out the propane structure and try moving the carbons about.

Sorry I ment octane.

1/ this isn't a 'we'll do your homeowrk for you' forum.

 

I know that this isn't for homework it is just an example of asking how to figure out an isomer of any hydrocarbon...

[Darkblade48]

To find all the possible isomers of octane, simply draw out all the chemical structures. For example, 2-methylheptane, 3-methylheptane and 4-methylheptane are just some examples...

 

From there, you can move down to hexane, pentane and butane, etc.
