Hey, y'all.
I know the oxidation state of a carbon in an ethene is -2 while carbon in Acetylene is -1. As well I know acetylene has more disspating elcetrons due to pai bonds. So how come charges between the acetylene carbon are more negative than in ethene while the carbones oxidations states are more negetive on ethene.
 
My main question is; Is there any connection between oxidation states and molecules charges areas or they are the absulute opposite?

Read what the caption says. The region of highest negative charge is not between the carbon atoms of acetylene.

So you say oxidation states is the charge between carbon atoms?

I didn't say anything at all about oxidation states.

So do you know if is there any connection between oxidation states and molecules charges areas?

Speaking for myself, I find that calculating oxidation numbers is a useful way to keep track of electrons.  I would not go so far as to say that there is no connection whatsoever with regions of electron density.  I am more inclined to say that oxidation states are a different sort of tool.
