SP Carbon Orbitals

  1. Jul 11, 2009 #1
    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?
