IDK if you can reply to this, but does the pi bond attached to the Oxygen count as a nucleophillic center as well? Or when a pi bond is on an open bond? Is there any exceptions to the pi bond rule?

Why does the the carbon center with three bonds have a full positive charge?

When a central carbon has four carbons connected to it, that carbon's going to be neutral. That's because it has 4 valence electrons that each get paired to one from all the other carbons. Each electron that pairs with that of the carbon gives it a slight negative charge. On the other hand, taking away one carbon removes an electron that pairs with the central carbon atom. So, removing a negative charge gives you a net positive charge. That central carbon center with three single bonds then gets a full positive charge because you took out the equivalent of one electron's worth of negative charge from it. Hope that helps!

So we're going to decide by the centre molecule being more electro negative or less

In aceton, the CH3 grops is going to donate electronrs ,so why woould the carbon be positiv?

Because in that group Carbon is the main donor.
