So once again, we have that same exact SP two SP two bond like we have here and we have 1234 SP three SP two bonds. So notice we have more stable bonds within this compound than this compound because SP two is more stable than SP three. Here, we only have one SP two SP three bond and the rest are SP three SP threes, while here, all four bonds are SP three SP two bonds. So in other words, electrons are more stable in the s orbitals. Thus, the more S character in a bond, the more stable that bond. And alkines are more stable when they have bonds with a lot of S character.
