Recall that a methylradical is simply a carbon atom attached to three H bonds or three H atoms via SP two hybridized orbitals. So each of these sigma bonds, covalent sigma bonds, are SP two hybridized. And we also have a pure two p orbital that contains a single electron within that two p orbital. So, to build this ethylene, let's simply replace the H atom here with a methylene atom with a ch two atom, or a ch two molecule. Sorry. What do we get?
