VSEPR w/ more than 1 central atom

[Ashita Tanwar 3H]

Is it possible to use VSEPR theory with atoms with more than one central atom? If it is, how do you write the VSEPR formula for molecules with more than one central atom?

I think we are supposed to say the VSEPR model per atom. For example C2H4, both labels would be trigonal planar. If it was C2H3O-, then we would label the C's as C1 and C2. C1 would be trigonal planar while C2 would be tetrahedral.

I agree. During my discussion section my TA did an example for a molecule with more than one central atom and he identified the molecular structure for each central atom.
