need isomer tables
 

Hi there,,
Im a high school student n im in need of some help
Well, I need a table for maximum number of structural(Constitutional) isomers for different compounds..For eg: I hav one for alkanes

Number of Constitutional Isomers of Alkanes.

Carbon Atoms Number of Isomers
4............ 2
5............ 3
6............ 5
7............ 9
8............ 18
9............ 35
10.......... 75
12.......... 355
15.......... 4,347
20 366,319


I need ones like these for alkenes,Alkynes,alchohols n all other groups if possible..Thanks

Good Luck. I suspect fractal theory could be used to afford some predictions. Too technical for me.

I have no idea where to find something like that. Sorry!

there is no "easy formula" for this problem.
has something to do with the "graphicstheory"?? or something like that
