In organic, it's a question of looking at the number of carbons, hydrogens, and other atoms and putting them in arrangements that satisfy that number.
In Inorganic, move the lone pairs around relative to the ligands to try to generate additional complexes.

There isn't a quantitative (exact) relationship between # of carbons and unique structural isomers (although there is an approximation) - unfortunately!
For the simplest compounds in organic chem (alkanes), here are the (grim) numbers:
Number of 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

well if you can arrange it differently with the same elements you have a different isomer.

yep it's C. the structure of the compound is different, you can get forms Cis-isomerism and Trans-isomerism, hope it helps i just had a chemistry exam today an its kinda stuck in my head.
