And we have a two p orbital on both of these carbons that has an electron in each orbital. So first, we let's examine what type of bond this carbon carbon bond is. So this carbon donates an SP two hybridized orbital. Remember, these guys are SP two hybridized. And this carbon also donates an SP two hybridized orbital. So when we combine two atomic orbitals, we must form two molecular orbitals according to quantum mechanics.
