Oxidation States of Molecules and Atoms and the Relationship with Charges

[Zohar]

TL;DR Summary

Oxidation state and charge

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?

Don't treat oxidation numbers too seriously, there is no measurable property of an atom that can be used to check them. They are more of an accounting device to help you balance reaction equations than a reflection of the reality.
