How many valence are in each molecule? I have Benzene, Dewar Benzene, Prismane, and 1,3,5 cyclohexatriene (which looks just like benzene but with different lengths between the $\ce{C-C}$ bonds). 

They are all $\ce{C_6H_6}$ chemical formula and I need to find out how many valence are in each molecule. I looked up what valence is but I'm confused if valence is the same thing as valence electrons or if valence is the amount of bonds the molecules can have. I think the amount of valence $\ce{H}$ can have is 1 but and $\ce{C}$ can have 4 so is the amount of valence 30?

i'm pretty sure the amount of valence electrons in all of them are 6.
I assume that the answer is that they are all C6H6 compounds (sorry for the terrible image!):



As others have pointed out in the comments, it doesn't really make sense to talk about the valency of a molecule. You could say they all have the same elemental formula, but then so do around 200 other molecules (in theory).
