Why and What are SP Carbon Orbitals When Hydrogens/Protons Removed?

[HeartSoul132]

When the hydrogens/protons are removed, leaving C-, can someone please tell me what and why the SP orbitals of these two carbons are?

Thanks.

On one it remains sp2 and on the other it is very likely a p orbital. You have to match up and explain which is which.

It seems like they are both sp2 to to me :O

For the carbon beta to the nitrogen, you show only one hydrogen where two exist. Remove one of the hydrogens (generating the C^- anion) and you have the electron in an orbital. Is that orbital hybridized as sp² or p?

For the carbon alpha to the nitrogen (the enamine carbon) the electrons in the C-H bond are clearly sp² before you remove the hydrogen and generate the anion. After you generate the anion, is that orbital hybridized as sp² or p?
