Okay, here is what I don't get about sp2 hybridization. So basically, I'll take CH3COCH3 as an example. So, there is a double bond between the C and the O.  So, the C is hybridized sp2. So this means, a full 1s orbital (obviously), followed by 3 half filled sp2 orbitals and 1 half filled 2p orbital which apparently makes the double bond with the O. Now, one of my sp2 orbitals will be filled by one sp3 electron from one of the CH3 and so will the other. Here is what I don't get, my manual says my double link is made by my 2p electron, but what happens to the other sp2 electron? I'm sorry if I don't use the right terms I am a french student and translated to the best of my ability. THank you!

in sp2 hybridization three equal bonding orbitols(sp2 orbitols) are formed by one s-orbitol and two p-orbitols.
This leaves one p-orbitol unmixed
it is the p orbitol that forms pie bond with the oxygen molecule
and the two sp2 orbitols forms sigma bond with CH3 and the other orbitol forms sigma bond with oxygen
